A =(b1+b2)h/2
actual b1 =10cm*10m/1cm =100m
actual b2 = 6cm*10m/1 cm = 60m
height = 5 cm*10m/1cm = 50m
A=(100+60)*50/2 = 160*50/2 =80*50= 4,000 m²
Answer : <span>C.=4,000 m²</span>
Answer:
he is correct he might have seen it's 3 times more than 18-29 which is 10% so he just multiplied 45 with 3
By minusing 12 to both sides
d+12=2
-12=-12
d =-10
Answer:
420cm^3 (cubed) = volume when tripled
Step-by-step explanation:
1. when you multiply 7*4*5=140 (volume of the prism originally)
2. 140*3=420 (final answer)
<span>Simplifying
u(x) = -2 + -2x + 7
Multiply u * x
ux = -2 + -2x + 7
Reorder the terms:
ux = -2 + 7 + -2x
Combine like terms: -2 + 7 = 5
ux = 5 + -2x
Solving
ux = 5 + -2x
Solving for variable 'u'.
Move all terms containing u to the left, all other terms to the right.
Divide each side by 'x'.
u = 5x-1 + -2
Simplifying
u = 5x-1 + -2
Reorder the terms:
u = -2 + 5x-1</span>
