Answer
D.pentagonal pyramid
Step-by-step explanation:
Answer:
length = (x − 8) units and width = (x − 9) units
Step-by-step explanation:
We need to factor
x^2 - 17x + 72
We need two numbers whose product is 72 and whose sum is -17.
The numbers are -8 and -9.
x^2 - 17x + 72 = (x - 8)(x - 9)
Answer: length = (x − 8) units and width = (x − 9) units
Answer:
.25x+1.75=15 and x=53
Step-by-step explanation:
first subtract 1.75 from both sides
then divide by .25 on both sides
and you will get x=53

Answer:
2250 m
Step-by-step explanation:
30 cm = 0.3 m
1 : 75 :: 0.3 : x
Product of extremes = product of means
1 *x = 75 * 0.30
x = 75 * 0.30
x = 22.5 m
