You simply divide 32 ÷ 4 = 8, for problem A
If by decomposition you mean breaking it ino parts then
break it itno 2 triangles and 1 rectangle
left to right
triangle with base y and height h
h=10
y=3
area of traignel=1/2bh
aera=1/2(10)(3)
area=5(3)
area=15
rectangel of legnth x and height h
area=legnth timwe width
x=8
h=10
area=8 times 10
aera=80
last triangle
should be same as other sinces same base (y) and same height (h)
15
add
15+80+15=120
Answer:
m = 28
Step-by-step explanation:
70 × 2 = 5m
140 = 5m
28 = m
Answer:
f(-1)=8
Step-by-step explanation:
Just plug in x=-1 into the function:
f(x)=6-2x
y=6-2(-1)
y=6+2
y=8
So f(-1)=8
You have to put numbers for what you want the area or perimeter to be and do accordingly
