mina [271]

Answer:

$486\ in^2$

Step-by-step explanation:

we know that

The surface area of the cube is equal to the area of its six square faces

$SA=6b^2$

where

b is the length side of the cube

we have

$b=9\ in$

substitute

$SA=6(9)^2=486\ in^2$

MN and KL are parallel. If JM = 7, MK = 21, and LN = 24, what is NJ? A. 8 B. 3 C. 10 D. 16

Reil [10]

We have from Thales theorem that because the 2 triangles are similar, JM/JK=JN/JL. We have that JN=x, JL=x+24 and that JM=7 and JK=28. Substituting, we get:
x/(x+24)=7/28.
Hence, x/(x+24)=1/4. This leads to 4x=x+24, 3x=24, x=8. We have solved for x=JN and this is equal to 8.
