Answer:

7(5 +2)

Step-by-step explanation:

From our knowledge of times tables, we know that ...

35 = 5·7

14 = 2·7

so the greatest common factor of 35 and 14 is 7. Factoring that out, we have ...

35 +14 = 7(5 +2)

Solve for x: (2/5)(x-4)=2x

NARA [144]

Simplify brackets

2/5(x - 4) = 2x

Simplify 2/5(x - 4) to 2(x - 4)/5

2(x - 4)/5 = 2x

Multiply both sides by 5

2(x - 4) = 10x

Divide both sides by 2

x - 4 = 5x

Subtract x from both sides

-4 = 5x - x

Simplify 5x - x to 4x

-4 = 4x

Divide both sides by 4

-1 = x

Switch sides

The width of a rectangle is 7 meters greater than its length. If the area of the rectangle is 170 square meters, write the quadr

soldier1979 [14.2K]

Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170

And that is the answer.
