Answer:
B and E
Step-by-step explanation:
A. Incorrect; the expanded form of 3(4x + 3) is 12x + 9
B. Correct; the cumulative property of addition was applied here.
C. Incorrect; this adds up to 8x + 52, which is not equivalent to 12x + 9
D. Incorrect; this equals 13
E. Correct; this is the expanded form of 3(4x + 3)

Answer:
Equation for the perimeter of prism's square face: 16x + 12
Step-by-step explanation:
Volume of Square prism = Length * Width * Height
= 144 x^3 + 216 x^2 +81 x
taking 9x common = 9x( 16 x^2 + 24 x + 9)
= 9x ( (4x)^2 + 2(4x)(3) + (3)^2 )
= 9x ( 4x+3)^2
so the length is 9x, width is 4x+3 and height is 4x+3
Now, Perimeter of prism's square face = 2* Width + 2 * Height
= 2* (4x+3) + 2* (4x+3)
= 8x +6 + 8x + 6
= 16x +12
Answer:
C.
Step-by-step explanation:
So basically set (10x-13) equal to (3x+22) and then solve for x
x=5
Plug 5 into the equations
(10(5)-13)=37
(3(5)+22)=37
These two angles are congruent due to the triangle being isosceles
37+37=74
All angles in a triangle are equal to 180 degrees
Therefore 180-74=106
Angle JKL= 106 degrees
Hope this helps :)
