Answer:

= (3t+2)(3t-2)(3t-4)

Step-by-step explanation:

Given the expression 27t^3 - 36t^2 - 12t + 16

On factoring:

(27t^3 - 36t^2) - (12t + 16)

= 9t²(3t-4)-4(3t-4)

= (9t²-4)(3t-4)

factoring 9t²-4

9t²-4 = (3t)² - 2²

From different of two square, a²-b² = (a+b)(a-b)

Hence (3t)² - 2² = (3t+2)(3t-2)

= (9t²-4)(3t-4)

= (3t+2)(3t-2)(3t-4)

Hence the factored form of the expression is (3t+2)(3t-2)(3t-4)

Solve -9m-4+2m = -9-7m+5, and interpret the results.
Drupady [299]

Answer:

-9m - 4 + 2m = -9 - 7m + 5

-7m - 4 = -7m - 4

-7m + 7m = -4 + 4

0 = 0

This is an identity solution because the same number equals the same number. That means there's an infinite set of solutions.

A small square of side 2x is cut from the corner of a rectangle with a width of 10 centimeters and length of 20 centimeters. Wri
love history [14]
Find the area of the rectangle. You can find the area of a rectangle with the following formula:

A = wl

w = width, and l = length.

Plug in your width and length:

20 * 10 = 200

The area of the rectangle is 200 square centimeters.

The area of a square is also given by width * length. Multiply the sides together:

2x * 2x = 4x^{2}

The area of a square is 4x^2.

Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:

200 - 4x^{2} cm^{2}
