(2x3 + 3x2 + 10x)(8x4)

The simplified form of the given expression is

Step-by-step explanation:

Given expression:

Now, we have to simplify the above so split into two term.

can be written as below, ‘x’ is taken out as it is common.

          -----> eq. 1

can be written as below, ‘8’ is cube of 2

          -----> eq 2

Now combine eq. 1 and 2, we get

When try to factoring , trinomial cannot be factored. Because,

Hence,

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

part a

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
