Answer:
26
Step-by-step explanation:
1.) Step plug it in ---} 4*2 + 7 (4) - 10
2.) Step multiply what u have so
4 x 2= 8
7 x 4 = 28
3. )Put it back ---} 8+ 28 - 10
4.) Solve from there.
8+28=36
36 - 10 =26
The sail is 3 ft tall
BxHx(1/2) =a
2.5x3x(1/2)= 3.75
7.2x(1/2)=3.75
3.5=3.5
I think the answer is y = -5/2x - 1, I'm doing the test right now.
I think:
a+a+2a+2a=180
6a=180
a=30
3x-12=x
2x=12
x=6
8-y=x
8-y=6
y=2
