Answer:
2x⁴ - x² - 15
Step-by-step explanation:
(X² - 3)(2x² + 5)
[x²(2x² + 5)] - [3(2x² + 5)]
= 2x⁴ - x² - 15
Answer:
13 and 27
Step-by-step explanation:
y= x+14
x+y=40
x+ x+14=40
2x+14=40
40-14=26
so, 2x=26
26/2
=13
so, x=13 and
and y equal 40-13
y=27
Answer:
No, he won't
Step-by-step explanation:
Given
Target = 480 pages in 28 days
Rate = 60 pages in 4 days
Required:
Determine if he'll reach his target
The rate can be expressed using:
So, we have:
Multiply the fraction by
This can be interpreted as: 420 pages in 28 days
And his target is 480 pages in 28 days
<em>Hence, he wont finish the book at that rate</em>
I assume this is by hand, but you can always check with a calculator
<span> 3(7 + 4)^2 − 14 ÷ 7
3(11)</span>² -- 14 ÷ 7
3(121) - 14÷7
363 - 2
= 361
Answer:
9 in = length
Step-by-step explanation:
The formula for the volume of a rectangular prism is V = LWH
Using this formula we get 2970 = 22(15)L
= 330L
L= 9 in = length
