Second and fourth pairs of rectangle are similar.
12x^2 + ax -20
if 3x + 4 is a factor of the expression above, what is the value of a?
Answer:
1
Step-by-step explanation:
(3x + 4)(px + q) = 12x^2 + ax - 20
3px^2 + 3qx + 4px + 4q = 12x^2 + ax - 20
3px^2 = 12x^2
p = 4
4q = -20
q = -5
px + q = 4x - 5
(3x + 4)(4x - 5) =
= 12x^2 - 15x + 16x - 20
= 12x^2 + x - 20
= 12x^2 + ax - 20
ax = x
a = 1

4.704=y+310
Enter your answer as a decimal in the box
Answer:
-305.296
Step-by-step explanation:
Make y the subject of the equation.
If 4.704=y+310 is the given equation, the value y is -305.3
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 4.704=y+310
Four point seven zero four equal to y plus three hundred ten
We need to solve for y in the given equation.
4.704=y+310
Subtract 310 on both sides
4.704-310=y+310-310
-305.3=y
Hence, y is -305.3 for the equation 4.704=y+310

А Two rays that share a common endpoint.
B.
The set of all points that are a fixed distance from a given point.
С
All points between and including two given points.
D
A straight path connecting two points and extending infinitely in both directions.
The only given option that correctly defines a line segment is;
Option C; All points between and including two given points.
In geometry in mathematics, a line segment is defined as a part of a line that is bounded by two distinct end points.
Now, let us look at the options;
Option A; This is not correct because a line segment must have 2 distinct endpoints
Option B; This is not correct because a line segment is a part of a line and not a set of points.
Option C; This is correct because it tallies with our definition of line segment.
Option D; This is not correct because a line segment does not extend infinitely.

Answer:
You want to find how much it cost for 1kg of potatoes, which in this case is .45 cents. After that you want to multiply the price of 1kg by 50, to get your cost for 50 kg of potatoes, which would be $22.50 I hope this helps! :)
Answer:
$22.50
Step-by-step explanation:
If one. again is 10k and it costs 4.50, then you would do 4.50 multiplied by 5 because each 10k is 4.50 and thier is 50 in total so 5 bags of 4.50 meaning 4.5x5 which would get you $22.50

Yes, these create an isosceles triangle, where two sides are equivalent
(x-y)(x-2y)+7x-10y+3
I need the answer quick pls. what is the Measure of the base of the area of the triangle is 25ft
Answer:
b = 12.5 ft
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here A = 25 and h = 4 , then
[tex]\frac{1}{2}[/tex] × 4 × b = 25 , that is
2b = 25 ( divide both sides by 2 )
b = 12.5 ft
The length of a rectangle measures 5/8 of a foot. The width of the rectangle measures 2 1/2 feet. What is the area of the rectangle?

OX= 1 & 5
Ox= -1 & 5
O x = 1 & -5
OX= -1 & -5
Answer:
x = -1
x = -5
Step-by-step explanation:
y= (x+3)^2 - 4
(x + 3)^2 = x^2+6x+9
y = x^2 + 6x + 9 - 4
y = x^2 + 6x + 5
x^2 + 6x = -5
x^2 + 6x + 9 = -5+9 (6/2=3, 3^2 = 9) (add 9 to both sides)
(x + 3)^2 = 4
x + 3 = sqrt 4
x + 3 = +- 2
x + 3= 2. x = 2-3. x = -1
x + 3 = -2. x = -3-2. x = -5
There were 768 towels on sale at the local store. 24 women purchased equal amounts of towels and left the shelf empty. How many towels did each woman purchase?
Answer:
Each women purchased 32 towels.
Step-by-step explanation:
Each women purchased 32 towels, because there are 768 towels in sale and 24 women, which mean each women take 32 from the 768. 768/24=768 or 24 women * 32 towels = the 168 towels on sale.

Answer:
Slope = -4
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, which means that multiplying their slopes result in a product of -1. Given the equation, x - 4y = - 12:
Transform the equation into its slope-intercept form, y = mx + b:
x - 4y = - 12
x - x - 4y = - x - 12
-4y = -x - 12
Divide both sides by -4:
[tex]\frac{-4y}{-4} = \frac{-x - 12}{-4}[/tex]
y = ¼x + 3 ⇒ (This is the slope-intercept form of the given standard equation, x - 4y = - 12).
Since the slope of the given equation is ¼, then it means that its negative reciprocal must be - 4:
(¼) (-4) = -1
Therefore, the slope of the line perpendicular to x - 4y = - 12 is - 4.

[tex]b=0.8[/tex]
Step-by-step explanation:
1) Subtract 2.7 from both sides.
[tex]-5.3-2.7=-\frac{b}{0.1}[/tex]
2) Simplify -5.3 - 2.7 to 8.
[tex]-8=-\frac{b}{0.1}[/tex]
3) Multiply both sides by 0.1.
[tex]-8[/tex] × [tex]0.1=-b[/tex]
4) Simplify - 8 × 0.1 to - 0.8.
[tex]-0.8=-b[/tex]
5) Multiply both sides by -1.
[tex]0.8=b[/tex]
6) Switch sides.
[tex]b=0.8[/tex]
Answer:
b=0.8
Step-by-step explanation:
[tex]\frac{b}{0.1} = 8\\b= (0.1)(8)\\b=0.8[/tex]
Pablo's family began their trip with a full tank of gas in their car. They drove 384.1 miles and
stopped to fill their tank back up with gas. It took 14.2 gallons of gas to fill up their tank.
About how many miles per gallon of gasoline did they average on their trip?
Work Shown:
(384.1 miles)/(14.2 gallons) = (384.1)/(14.2) mpg = 27.049 mpg approximately
mpg = miles per gallon
Answer:
27.05 miles per gallon
Step-by-step explanation:
384.1 miles = 14.2 gallons
x = 1 gallon
14.2x = 384.1
x = 384.1/14.2
= 27.0492958
≈ 27.05 miles per gallon
