Answer:
Area = (a² -5a) in²
Perimeter = (4a -10) in
Step-by-step explanation:
Let the length of the rectangle be a.
Given that, its width is 5 in less than the length.
So,
length ⇒ a
width ⇒ (a - 5)
First, let's find the area of the rectangle.
Area = length × width
Area = a ( a - 5 )
<em>Solve the brackets.</em>
Area = <u>(a² -5a) in²</u>
<u />
Now, let us find the perimeter of the rectangle.
Perimeter = 2 ( l + w )
Perimeter = 2 ( a + a - 5 )
Perimeter = 2 ( 2a - 5 )
Perimeter = <u>(4a -10) in</u>
Answer:
B
Step-by-step explanation:
Answer:
- 7, - 28, - 112, - 448, - 1792, - 7168
Step-by-step explanation:
Using the recursive formula and a₁ = - 7 , then
a₂ = 4a₁ = 4 (- 7) = - 28
a₃ = 4a₂ = 4(- 28) = - 112
a₄ = 4a₃ = 4(- 112) = - 448
a₅ = 4a₄ = 4(- 448) = - 1792
a₆ = 4a₅ = 4(- 1792) = - 7168
idk how to help you sorry :(
Answer:
Male=21 Female=14
Step-by-step explanation:
So the problem would be (f)+(f+7)=35
first you would subtract 7 from 35
Now you have (f)+(f)=28 or 2f=28
Then you divide both sides by two
f=14
and since we know there is 7 more males then the answer is
m=21
