Answer:
s. -30
Step-by-step explanation:
All the angles in a triangle equal 180 so:
-2x - x + 90 = 180
add like terms
-3x + 90 = 180
subtracts 90 from both sides
-3x = 90
divide both sides by -3
x = -30
24*2 is the answer I thonk
This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone
Did you ever get the answer to this?
Answer:
99
Step-by-step explanation:
First you find the area of the big rectangle:
15x9=135
Then, you need to find the area for the smaller square:
6x6= 36 (because in a sqaure all sides are the same)
Finally, you have to subtract 135 from 36
135-36=99
So, your answer is 99
