Answer:
D
Step-by-step explanation:
Answer:
3a+6
Step-by-step explanation:
3a+6 = 24a+48 divided by 8 (there are 8 sides in an octagon)
covert 24a +48 inches into feet
2a+4 feet = 18 feet
subtract 4 from both sides
2a = 14
divided 2 from both sides
a = 7
covert 3a+6 inches into feet
0.25a +0,5
0.25(7)+0.5
= 2.25
verify your answer
2.25 x 8 = 18
Similar steps:
1. You need to draw a reference line first( It's trivial but hey, it's similar)
2. You need to draw the other line with pre-defined slope( parallel with same slope, perpendicular with the product of the slope to be -1)
Answer:
a.)48
b.)528
c.)448
Step-by-step explanation:
a.)8x8=64. 4x4=16 64-16=48
b.)48(from a. answer)x11=528
c.)11x8(x2 for the other side)=176. 11x4x4=176.
48x2=96. 176+176+96=448
