10x-7(3x+8)=-26x+4
first you have to isolate the variable
then you divide each side by factores that don't contain the vairable
for this problem if you follow those steps
X=4
-7(3x+8)=-36x+4
-11(3x+8)=-36x+4
Answer:
150cm2
Step-by-step explanation:
A=6a2, where a is the side of one face of the cube. Given a=5cm
A=6(5cm)^2
=6×25cm^2
=150cm^2 or 150cm2
The expression that represents the volume would be: <span>C) 6x^3+39x^2+54x</span>
Proof of the calculation:
V = Lwh
V = (x+2) (3x) (2x+9)
V= (3x^2 + 6x) (2x + 9)
V = (6x^3 + 27X^2 +12x^2 + 54x)
V = 6x^3 + 39x^2 + 54x
Step-by-step explanation:
Perimeter of a rectangle= 2(l+b)
= 2( 4m-1+3m+2)
=2(7m+1)
= 14m+2
