Answer:5
Step-by-step explanation:
Answer:
(x+10) and (x-10)
Step-by-step explanation:
The volume of a rectangular box is defined as
Volume = width*height*length
In this case
Volume = 6x^2-600 = 6*(x^2 - 100)
And we also know,
Volume = (6)*height*length
So,
6*(x^2 - 100) = (6)*height*length
This means that
height*length = (x^2 - 100)
height*length = (x+10)*(x-10)
Answer:
3.) 11
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 5
f(3) is x = 3
<u>Step 2: Solve</u>
- Substitute: f(3) = 2(3) + 5
- Multiply: f(3) = 6 + 5
- Add: f(3) = 11
Answer:
-8+2r=6.
2r=8+6
r=7
Step-by-step explanation:
Answer:
-1199
Step-by-step explanation:
To solve this, we must use PEMDAS
1. using this, we see that we must first solve anything having to do with exponents so:
4^2 = 16
2. Then we must solve any multiplication or division (whichever comes first). So in this case:
5 x 243 = 1215
3. We are now left with 16 - 1215 so we simply subtract
16 - 1215 = -1199
