Select all the expressions that are equivalent to x2+4x. (^2 means raising something to the 2nd power.)
Answer:
(x+4)x
Step-by-step explanation:
The factor of the expression into an equivalent form x² + 4x would be; x(x + 4)
What are equivalent expressions?Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We need to factor the expression into an equivalent form x² + 4x
This expression could also be given by;
x² + 4x
Then factor out x we get;
x² + 4x = x(x + 4)
Hence, the expression into an equivalent form x² + 4x would be; x(x + 4)

Can someone please help me
Answer:
19.0 cm
Step-by-step explanation:
a^2+b^2=c^2
1^2+b^2=19^2
1+b^2=361
(subtract one from both sides)
b^2=360
(now square root to get rid of the ^2)
[tex]\sqrt{b^2}[/tex]=[tex]\sqrt{360}[/tex]
b=18.97 rounded to the tenths place is 19.0
Answer:
The length of the other leg is 19 cm (rounded to the nearest tenth).
Step-by-step explanation:
In order to solve this, we need to know the Pythagoras theorem which states that...
[tex]c^{2} = a^{2} +b^{2}[/tex] (Where c is the length of the hypotenuse and a and b are the lengths of the legs)
Now just substitute the values to find the length of the other leg, and we get...
[tex]c^{2} = a^{2} +b^{2}\\19^{2} = 1^{2} + b^{2} \\b^{2} = 19^{2} - 1^{2} \\b^{2} = 361 - 1\\b^{2} = 360\\b = \sqrt{360} \\[/tex]
b ≅ 19
Therefore the length of the other leg is around 19 cm.
[tex]\sqrt{176[/tex]

Find the radius of a sphere with a volume of 180 cubic feet. Round your answer to the nearest tenth.
Answer:
3.50ft
Step-by-step explanation:
Given data
Volume= 180ft^3
The expression for the volume of a sphere is given as
Volume=4/3πr^3
substitute
180=4/3*3.142*r^3
180=12.568/3*r^3
180=4.189*r^3
r^3= 180/4.189
r^3= 42.969
cube root both sides
r= ∛ 42.969
r= 3.50ft
Hence the radius is 3.50ft
Solve for x LT1 10th grade level
Answer:
x = 5
Step-by-step explanation:
Because the red-marked lines are parallel, we know that the ratios are the same
5x : 45 = 20 : 36
5x/45 = 20/36
5x * 36 = 20 * 45
5x * 4 = 20 * 5
5x * 1 = 5 * 5
x = 5

a spinner has 8 equal sections,6 are green .find probability that will land on green
Answer:
P(A) and P(B) = P(A) x P(B)
P(A) = number gray/total number of sections = 6/8 = 3/4
P(B) = number of reggae songs/total number of songs = 2/8 = 1/4
P(A) and P(B) = (3/4)(1/4) = 3/16
Step-by-step explanation:
Answer: 3/4 (0.75)
Step-by-step explanation:
6 out of 8 sections are green.
So there is a 6/8 probability that it will land on green.
6/8 = 3/4.

I need help with this elimination problem
Add up the same sides of both equations to eliminate x :
(x - 2y) + (-x + 3y) = 8 + (-5)
(x - x) + (-2y + 3y) = 8 - 5
y = 3
Then
x - 2y = x - 6 = 8 → x = 14

Answer:
D. 17
Step-by-step explanation:
1. Set up an equation (2x + 5) + (3x + 10) = 100
2. 2x + 3x= 5x and 5 + 10 = 15
3. The equation simplified 5x + 15 = 100
4. Move the 15 to the other side of the equation. 5x = 100 - 15
5. 5x = 85
6. Finally, divide 85/5
7. Our final answer is 17.

factorise x squared - 3x
Answer:
x squared -3× =x(x-3)
Step-by-step explanation:
Since the common factor is x,one comes out to multiply the other to give it x squared and since one x has been written outside already we just write the 3 so that when we multiply it we will get the answer we were asked to factorise
Describe the properties of equality that Kira used. The first step is to use the property of equality to combine the constant terms. The second step is to use the property of equality to isolate the variable.
Answer:
1. Subtraction property
2. Division property
Step-by-step explanation:
Question has missing details.
Kira's steps are:
[tex]\frac{7}{2} - 2x = \frac{11}{2}[/tex]
[tex]\frac{7}{2}- \frac{7}{2} - 2x = \frac{11}{2}- \frac{7}{2}[/tex]
[tex]- 2x \div -2= \frac{4}{2} \div -2[/tex]
[tex]x = -1[/tex]
Required
The properties used
For the first step, we have:
[tex]\frac{7}{2} - 2x = \frac{11}{2}[/tex]
To get to step 2, Kira subtracted [tex]\frac{7}{2}[/tex] from both sides.
i.e.
[tex]\frac{7}{2}- \frac{7}{2} - 2x = \frac{11}{2}- \frac{7}{2}[/tex]
This property is subtraction property
In the second step, where x is isolated.
[tex]- 2x \div -2= \frac{4}{2} \div -2[/tex]
Both sides of the equation were divided by -2 to give:
[tex]x = -1[/tex]
This property is division property

Algunos estudiantes se repartieron una bolsa de galletas. Todos tomaron la misma cantidad y sobraron 5
Fig. A shows a paper cup in the shape of an inverted right circular cone. Its base radius is 4 cm and its slant height is 8.5 cm.
(a) Find the capacity of the paper cup.
(b) The paper cup is cut along PQ to form the sector in Fig. B. Find
(i) the area of the sector,
(ii) the angle of the sector.
(a)
Height of the cup
= [tex]\sqrt{ {8.5}^{2} - {4}^{2} }[/tex]
= 7.5 cm
The capacity of the cup
= [tex] \frac{1}{3} \times \pi \times {4}^{2} \times 7.5[/tex]
= 126 cm³ (cor. to 3 sig. fig.)
(b)(i)
The area of the sector
= [tex]\pi \times 4 \times 8.5[/tex]
= 107 cm² (cor. to 3 sig. fig.)
Can you help me for (b)(ii)?
9514 1404 393
Answer:
16π/17 radians ≈ 169.41°
Step-by-step explanation:
The arc length of the sector is the circumference of the cone:
C = 2πr = 2π(4 cm) = 8π cm
The angle and arc length are related by ...
s = rθ . . . . . θ in radians
8π cm = (8.5 cm)θ
θ = 8π/8.5 = 16π/17 . . . . radians
bii) The angle of the sector is 16π/17 radians ≈ 169.41°.
Answer:
169° (3sf)
Step-by-step explanation:
the area of a circle multiplied by the angle over 360 gives you ans.
x/360 × π × r²=34π -> ur ans frm part i
x × π(8.5²)=12240π
x × 72.25=12240
x=169.41°
