Answer:
D
Step-by-step explanation:
Height: h
Length: 2h + 15
Area = length × width
4h² + 42h + 90
2(2h² + 21h + 45)
2[2h² + 15h + 6h + 45]
2[h(2h + 15) + 3(2h + 15)]
2(h + 3)(2h + 15)
Width = 2(h+3) = 2h + 6
Length: 2h + 15
Difference:
(2h + 15) - (2h + 6)
2h + 15 - 2h - 6
9
Width is 9 feet shorter than the length
Answer:B
Step-by-step explanation:
65•7
39/50= 0.78 times 100= 78
78 is Donovan's score
if maci's score is 10 percentage points higher
78+10=88
x /50 =0.88 times 100= 88
x=44
each question is 2 points: 88-78= 10/2=5
Maci answered 5 questions correctly.
Answer:
x=50
Step-by-step explanation:
65+65=130
180-130=50
We are given statement : The distance between Pittsburgh, Pennsylvania, and St. Louis, Missouri, is 17 miles less than 5 times the distance between Pittsburgh and Cleveland, Ohio.
The distance between Pittsburgh and Cleveland = d.
We need to write an expression for distance between Pittsburgh and St. Louis.
And it's "17 miles less than 5 times the d".
5 times of d is = 5d.
17 miles less than 5d = 5d -17.
Therefore, 5d -17 expression can you use to represent the distance between Pittsburgh and St. Louis.
