Answer:

c ( x - 5 ) ( x + 3 ) ( x - 1 )

Step-by-step explanation:

if you multiply the first two brackets you would get x² - 2 - 15, for example x × x will give you x² x × 5 will give you 5x and so on ( basically you need to use the FOIL method )

to get x² + 2x - 3 multiply the second and third brackets with each other just like how you did for the first one.

I'm not sure if that's what you wanted...

What is £56 divided in a ratio of 3:5?

Luda [366]

First, add the ratio together to get the denominator of the fraction you will use to determine the share. 3+5= 8. Now, you have two fractions: 3/8 and 5/8. Next, just find 3/8 and 5/8 of 56 to get your answers:
(56÷8)×3= £21
and
(56÷8)×5= £35

A prism with a triangular base has a volume of 432 cubic feet. The height of the prism is 8

Rashid [163]

Answer:

9 feet

Step-by-step explanation:

Given:

A prism with a triangular base has a volume of 432 cubic feet.

The height of the prism is 8.

The triangle base has a base of 12 feet.

Question asked:

The height of the triangular base of the prism = ?

solution:

Volume of triangular prism = $Area of triangle \times height$

$432 = Area of triangle \times8$

Dividing both side by 8

$54 = Area of triangle$

$54 =$ $\frac{1}{2} \times base \times height$

$54 = \frac{1}{2} \times12\times height\\54 = \frac{12}{2} \times height$

Multiplying both side by 2

$108 = 12 \times height$

Dividing both side by 12

$9 = height$

Thus, height of the triangular base of the prism is 9

What is the answer to the equation -2x-8=-10

Oxana [17]

You need to get "x" by itself on one side

$-2x-8=-10$

Add positive eight on both sides---because its the opposite of negaitve

$-2x-8+8=-10+8$

$-2x=-2$

Divide -2 by -2

-2÷-2=1

 $x=1$
