Answer:

31.5

Step-by-step explanation:

Area of a rectangle = lw

Substitute: 7*3 = 21

Area of a Triangle = 1/2*bh

Substitute: 1/2*(3)(7) = 10.5

Area = 21 + 10.5 = 31.5

How do you solve this problem? (x+3) cubed
Lubov Fominskaja [6]
You would expand becausee it isn't equal to anything

(x+3)^3=(x+3)(x+3)(x+3)
we can use binomial theorem or pascal's triangle
anyway, pascal's triangle is more practicl for this one

so
for the 3rd power
(a+b)^3=1a^3+3a^2b^1+3a^1b^2+1b^3

a=x
b=3

(x+3)^3=1x^3+3x^2(3^1)+3x^1(3)^2+1(3)^3=
x^3+9x^2+27x+27
