The answer is 12 m.

How to solve:

First find out the height of the bottom square, which is done by doing 3 x 3 which gives you 9

Next find out the height of the triangle by doing 5 - 3 which gives you 2

Find out the area of the triangle by doing 2 x 3 which gives you 6. 6 is not the area of one triangle but of two of them as a square. You need to divide 6 by 2 in order to find out the area of the triangle. This gives you 3.

3 + 9 = 12

"-3 = 9/5c + 32" help with finding c pls!! i need it as a decimal btw.
Serggg [28]

Answer:

-3=9/5c +32

-3*5c=9/5c*5c+32*5c

-15c=9+160c

-15c -160c =9

c(-15-160)=9

c(-15-160)/(-15-160)=9/(-15-160)

c=9/(-15-160)

<span>so use pythagorean theorem where
a^2+b^2=c^2
a and b are legs
c=hypotonuse
in a right triangle

90 degrees=right riangle
so we have 20 and 15
these are the legs
subsitute
20^2+15^2=c^2
400+225=c^2
add
625=c^2
square root both sides
25=c
new pipe=25
how much shorter
old=20+15=35
how much shorter is 25 than 35
35-25=10
answer is 10 miles</span>

Solve for x: 5|2x − 2| + 8 = 18.
Tju [1.3M]
Remember
|x| makes x posotive
5|2x-2|+8=18
minus 8 both sides
5|2x-2|=10
divide both sides by 5
|2x-2|=2
assume
2x-2=2 and 2x-2=-2

2x-2=2
add 2
2x=4
divide 2
x=2

2x-2=-2
add 2
2x=0
x=0


x=0 or x=2
