The length of a rectangle is (x+5) and the width is (x+2). The area of the rectangle is 70 square feet. What is the length of th
vaieri [72.5K]

Answer:

The length of the rectangle is 30 feet.

Step-by-step explanation:

Because the equation for area is length times width, you would have to set the two equations to seventy and multiply them.

<em>     (x+5) (x+2) = 70</em>

<em>     </em><em>2x + 10 = 70</em>

Then, you would have to subtract ten from both sides, cancelling it from the left side.

<em>     2x = 60</em>

<em />

Then do the opposite and divide sixty by two, therefore getting a length of thirty feet.

Three added to eight times a number is the same as three times the value of two times the number -1
emmainna [20.7K]

Answer:

The number x is -3

Therefore x=-3

Step-by-step explanation:

Given problem is "Three added to eight times a number is the same as three times the value of two times the number -1"

Let x be the number

It can be written as

3+8\times x=3(2\times x-1)

3+8x=3(2x-1)  ( applying the distributive property )

3+8x=3(2x)+3(-1)

3+8x=6x-3

subtracting (6x-3) on both sides we get

3+8x-(6x-3)=6x-3-(6x-3)

3+8x-6x+3=6x-3-6x+3

6+2x=0 ( ading the like terms )

2x=-6

x=-\frac{6}{2}

Therefore x=-3

The number x is -3
