Simplify the product.
liberstina [14]

The value of the product expression is –6p^3 + 8p^2 – 10p

<h3>How to simplify the product?</h3>

The product expression is given as:

2p(–3p2 + 4p – 5)

Rewrite properly as:

2p(–3p^2 + 4p – 5)

Remove the bracket

2p * –3p^2 + 2p * 4p – 2p * 5

Evaluate the products

–6p^3 + 8p^2 – 10p

Hence, the value of the product expression is –6p^3 + 8p^2 – 10p

LOOK AT THE PICTURE BELOW
Katyanochek1 [597]

Answer:

The area of the rectangle is 40 and the area is the triangle is 20 therefore, the area of the shape is 60

Step-by-step explanation:

Rectangle:

8cm x 5cm = 40cm

Triangle <em>(</em><em>1</em><em>/</em><em>2bxh</em><em>)</em>

The base of the triangle would be 8 cm as the top and the bottom of the rectangle is the same width. The height was given to be 5 cm (<em>note the height is the dotted line</em>) Therefore the area of the triangle is half the base which is (8×1/2 = 4) times the height (5); which is 20.

Find the surface area of the right rectangular prisim
Vlad [161]

Answer:

46 units^2

Step-by-step explanation:

The formula for surface area of a rectangular prism is

SA = 2(lw +lh+wh)  where l is length, w is width and h is height

SA = 2 (2.5* 4+ 2.5*2 + 4*2)

      = 2 (10+5+8)

       = 2( 23)

       = 46 units^2

You put $500 in a savings account. The account earns $15.75 simple interest in 6 months. What is the annual interest rate?
Anettt [7]

Answer:

6.3%

Step-by-step explanation:

We're gonna use the simple interest formula: A = P(1 + rt)

A = Final amount (500 + 15.75 = 515.75)

P = Starting amount (500)

r = rate (?)

t = number of years (.5 since it's been half a year)

515.75 = 500(1 + 0.5r)

Disitribute the 500 to the equation inside the parenthesis

515.75 = 500 + 250r

Subtract 500 from both sides

515.75 = 500 + 250r

- 500   - 500

15.75 = 250r

Divide both sides by 250

15.75/250 = 250r/250

r = 0.063
