Answer:
9.055
Step-by-step explanation:
12.7 - 4.705 = 7.995
7.995 + 1.06 = 9.055
<span>(f+g)(x) = f(x) +g(x)
= (7x^3 −2x−12) +(−3x^3 -8x^2 +10x</span>)
= x^3(7 -3) +x^2(-8) +x(-2+10) +(-12)
= 4x^3 -8x^2 +8x -12
Corresponds to selection C.
Answer:
Width: 15 cm
Area: 150 cm squared
Step-by-step explanation:
I did 10 + 10 to get the total of the two sides of the rectangle.
I subtracted 20 from 50 to get what the two widths are supposed to add up to.
The answer was 30 so I divided 30 by 2 to get what one width equals.
The width equals 15.
To get the area of a rectangle you have to multiply the length by the width which would be 150 cm squared.
