Tanzania [10]2 years ago
8 0

Answer:

P = 20

Step-by-step explanation:

Hello!

We can solve this by substituting -4 for t.

<h3>Evaluate</h3>
  • P = 3t² + 7t
  • P = 3(-4²) + 7(-4)

<u>Remember that any negative number squared is the absolute value of that number squared.</u>

  • P = 3(|-16|)  - 28
  • P = 3(16) - 28
  • P = 48 - 28
  • P = 20

The final evaluation is 20.

Katyanochek1 [597]

The unit measurement of the a volume in mm is mm³(millimetres cube.)

<h3>How to find volume ?</h3>

Volume is is defined as the space occupied within the boundaries. The objects are usually solid objects.

The volume of a 3 dimensional figure is the product of the base area and the height.

Therefore, the units of volume is measured in cubic units.

The volume of a prism with side lengths measured in millimetres is 20.

Therefore, the measurement can be represented as follows:

20 mm³

Answer:

X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2

Step-by-step explanation:

X + (2 and 1/2) - 3/4 = 5 and 1/4

X + 2 and 2/4  - 3/4 = 5 and 1/4  <--- common denominator

X + 10/4 - 3/4 = 21/4

X + 7/4 = 21/4

X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2
