Answer:
Quadratic binomial
Step-by-step explanation:
4x(x+1) - (3x-8)(x+4)
Open parenthesis
(4x^2+4x) - (3x^2+12x-8x-32)
(4x^2+4x - 3x^2-12x+8x+32)
Collect like terms
4x^2-3x^2+4x+8x-12x+32
=x^2+32
Answer: 544?
This is the answer if I'm supposed to solve the question in yellow
1/2*16(48+20) = 1/2*16*(68)
1/2*16=8
8*68 = 544
630m³
volume= 7m×9m×10m=630m³
x = 24
10:8
10(3) = x(3)
x = 8
30 : 24
