The area of a rectangle is 128 sq. ft. If the width is twice the length, what is the measure of the length of the rectangle?

Answers

Answer 1
Answer: Length is 8 and width is 16. I hope this helps!
Answer 2
Answer: We calculate the area of ​​a rectangle with the equation

A = LW*1/2
A = The area of a rectangle
L = the height of the triangle
W = the base of the triangle

If the equation is one unknown to solve them quickly .
A = 128sq.ft
L = ?
W = 2L

substitute values ​​into the formula

A = L * W *1/2
128sq.ft = Lft. * (2Lft) *1/2
128 = L²
L = √128 = 8√2

W = 2L = 2*8√2 = 16√2

Which equation could be used to solve the problem? Tony is on a train that travels 99 mi in 1 h.

At that rate, how many miles (d) will the train travel in 9 h ?

A.
d = 99 + 9

B.
d = 99 ÷ 9

C.
d = 9 ÷ 99

D.
d = 99 • 9

Answers

it is D you will have to Multiply because its say How many mile so thats how i find out
The equation is D. If the train goes 99 miles per 1 hour thats 99 multiplied by 1. But if you substitue the 9 in for the 1 then its 99 times 9:)

Find GCF of x^6 and x^5

Answers

x^6 = x * x * x * x * x * x

x^5 = x * x * x * x * x

The GCF is the greatest number of xs that each has in common. They are in bold. There are 5 xs that each of the terms have.

GCF = x^5

x^6 = x^5 * x

So GCF of x^6 and x^5 = x^5

Two numbers have their own reciprocals. What are they?

Answers

The two numbers that are the same as their reciprocal are 1 and -1.

The reciprocal of a/b is b/a.

The reciprocal of 1 is 1.

1 is nothing but 1/1. And if you flip the numerator and denominator, you get 1/1 which is 1.

The reciprocal of -1 is -1.

-1 is nothing but -1/1. And if you flip the numerator and denominator, you get 1/-1 which is -1.

The only two numbers that have their own reciprocals are 1 and -1.
The two numbers that have their own reciprocals is 1 and -1
