Answer: D) 85
Step-by-step explanation:
The area of a rectangular prism is length * width * height(5*3.4*5)
5 * 3.4 * 5 = 85
Answer:-
0
Step-by-step explanation:
h(x) = x^2 + 2x -3
x = 2
h(2) = 2^2 + 2(2) - 3
h(2) = 4 + 4 - 3
h(2) = 8-3
h(2) = 5
x = - 4
h(-4) = (-4)^2 + 2(-4) - 3
h(-4) = 16 - 8 - 3
h(-4) = 16 - 11
h(-4) = 5
========
h(2) - h(-4)
5 - 5
0
Answer:
x ≈ 80.4
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan15° =
=
( multiply both sides by 300 )
300 × tan15° = x , then
x ≈ 80.4 ( to the nearest tenth )
Option C
When
is subtracted from
then the result is 
<h3><u>Solution:</u></h3>
Given that
is subtracted from 
We have to find the result
Subtraction is a mathematical operation that tells us the difference between two numbers.
When "a" is subtracted from "b", we write in mathematical expression as "b - a"
So
is subtracted from
is written mathematically as:

<em><u>Expanding the above expression using algebraic identity:</u></em>


Multiplying the nnegative sign with terms inside bracket
<em><u>There are two simple rules to remember: </u></em>
- When you multiply a negative number by a positive number then the product is always negative.
- When you multiply two negative numbers or two positive numbers then the product is always positive.

Hence the result is:
