A rectangle has a perimeter of 25 meters. If the lengths of the sides of the rectangle are multiplied by 7 to make a new rectang
juin [17]

Answer:

175 m

Step-by-step explanation:

We are given;

  • The perimeter of a rectangle as 25 m

We are required to determine the new perimeter if the sides of the rectangle are multiplied by 7.

We know that;

Perimeter of a rectangle = 2(L+W)

Therefore, initially;

2(L+W) = 25 m

Hence;

L + W = 12.5 m

if the sides are multiplied by 7, then;

New length = 7L

New Width = 7W

Thus;

New perimeter = 2(7L+7W)

                         = 14 (L + W)

but, L + W = 12.5

Thus;

New perimeter = 14 (12.5)

                         = 175 m

Therefore, the new perimeter will be 175 m

Rewrite the following quadratic functions in intercept or factored form. Show your work.
Vlad [161]

Answer:

y = (2x + 3)(2x + 3) = (2x + 3)²

Step-by-step explanation:

We are given a quadratic function and we have to write it in factored form.

y = 9 + 12x + 4x²

y = 4x² + 12x + 9

We can break the mid-term in such a way that when they are multiplied, the factors give a product of 36x² and when added, they give a result of 12x, as show below:

y = 4x² + 6x + 6x + 9

Taking 2x common from the first two variables and 3 from the second two

y = 2x(2x + 3) + 3(2x + 3)

Taking 2x+3 common

y = (2x + 3)(2x + 3) = (2x + 3)²
