Answer:
x = 5.4
Step-by-step explanation:
(This question has already been answered, but both of the incorrect ones were deleted, so for future reference...)
Fig A is a scale image of Fig D. These two quadrilaterals are similar, and thus, the side lengths of corresponding sides are proportional. Set the proportion x/3 = 7.2/4 (you could alternatively write it as x/7.2 = 3/4 but for the simplicity's sake, and assuming anyone who has this problem would already know how to solve proportions like these...)
7.2/4 = 1.8
so
x/3 = 1.8
now multiply both sides by 3 to get x = 5.4
Answer:
Jenna needs 2 yards of ribbon to wrap 4 boxes.
Step-by-step explanation:
First, we can find how many inches of ribbon she needs.
18*4=72
She needs 72 inches of ribbon for 4 yards.
There are 36 inches in a yard.
72/36=2
Jenna needs 2 yards of ribbon to wrap 4 boxes.
Answer:
An octagon has eight interior angles.
Interior angle total sum = (n-2) x 180, where n = number of sides.
Since an octagon has 8 sides, we have:
6 x 180 / 8, which is 135.
The answer is 135.

Answer:
Tina
Step-by-step explanation:
bc if you sub in 4 for x the equations on both sides are 0
check:
-4 + 4 = 0 -3 x 4 = -12
0 x 3 = 0 12 + -12 = 0
0 = 0
please mark this as brainiest!!!!
Answer:
182
Step-by-step explanation:
The correct answer is 182 because to figure out the total we needed to multiply the 2 sides, a quicker way instead of counting. To do this you needed to multiply 13 times 14 and you would get 182!
Hope this helped!
