What are the solutions of (x - 3)(2x + 4) = 0
Answers
Step-by-step explanation:
(x - 3 ) (2x + 4) = 0
Either
x - 3 = 0
Therefore x = 3
Or.,
2x + 4 = 0
2x = - 4
x = - 4 /2
Therefore x = -2
Now the value of x is 3 or - 2.
Hope it will help :)♥
Answer:
x = 3 & x = -2
Step-by-step explanation:
(x-3) = 0 so x = 3
(2x+4) = 0 so 2x = -4 x = -2
The distance from the bottom of a ladder to the wall it leans against is one-fourth of the length of the ladder. If the ladder is 12 feet long, how far up the wall will the ladder extend?
Answers
Answer:
The ladder will extend 11.6ft up the wall
Wall will the ladder extend 11.6 ft
What is Pythagoras theorem?The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Given
Length of the ladder = 12 ft
Distance from the bottom = 1/4 of length of the ladder
= [tex]\frac{1}{4}[/tex] × [tex]12[/tex]
= 3 ft
By using Pythagoras theorem
[tex]12^{2}=x^{2} +3^{2}[/tex]
[tex]x^{2} =144-9[/tex]
[tex]x^{2} =135[/tex]
[tex]x=\sqrt{135}[/tex]
[tex]x=[/tex] ± 11.6 ft
Hence, wall will the ladder extend 11.6 ft.

Caitlin earns $7.00 an hour doing yard work for her neighbor. She worked 3 hours Friday, 4 hours Saturday, and more hours Sunday. She earned $77.00 for the weekend. How many hours did she do yard work on Sunday?
Answers
Answer: 4 hours
Step-by-step explanation:
$77.00 divided by $7.00 = 11 hours
11 hours- 3 hours (Friday)- 4 hours (Saturday)= 4 hours on Sunday
A total of 7 hours worked on Fri. and Sat.
Answer:
Caitlin worked 4 hours on Sunday.
Step-by-step explanation:
The answer is 4 hours because 7.00 multiplied by 7 (Because 3 + 4 = 7) is 49.00 and 77.00 minus 49.00 = 28.00 and since 1 hour = 7.00 and 7.00 multiplied by 4 is 28.00 then the answer must be 4 hours.

Step-by-step explanation:
Let x be Savannah's age
Ahsleys age should be 4 years less than three times Savannah's age
3x (Savannah) - 4 (years)

Below are two parallel lines with a third line intersecting them.
Answers
Answer:
132 degrees
Step-by-step explanation:
One sit of the 48 degrees is 48 degrees, so that opposite will be the same. Add them up, get 96. There is a full 360 degrees circle, so get 360 and subtract 96 from it, to get 264 degrees. That is the top and bottom angle of the right side, so just divide it in two
Answer:
I think x= 84
if the lines are parallel then the angle should be the same. Because one angle =48° the other side is likely to equal the same. Add 48+48, subtract 180 from your answer and that's how you get 84°. hope this helps

11. The distance between two houses in a neighborhood is 12 meters. There are approximately 4 meters in 13 feet. Which measurement, in feet, is closest to the distance between the two houses?
Answers
Answer:
The closest distance between the houses in feet is 39 feet
Step-by-step explanation:
Distance between the houses in metres is 12 metres.
Essentially, the problem is asking us to convert this distance to feet using the scale ratio that we are given.
The scale ratio is
4 meters = 13 feet.
1 meter = x feet
by cross multiplying, we have that x = 13/4 feet
We now know how long 1 meter is in feet using the scale we were given
We can now convert the 12 meters to feet.
1 meter = 13/4 feet
12 meters = x feet
[tex]x = 12 \times 13/4=39 feet[/tex]
Therefore, the closest distance between the houses in feet is 39 feet

Given the expression
3 -x = 2+x
We re to find the number of solutions we will have:
Subtract 2 from both sides
3-x-3 = 2+x -3
-x = x -1
subtract x from both sides
-x - x = x - 1 - x
-2x =-1
Divide both sides by -2
-2x/-2 = -1/-2
x = 1/2
Since the value of x is just 1, hence the equation has just one solution.
