Answer:
Step-by-step explanation:
So, it's x*x+x*-3+-4*x+3*-3
That simplifies to x^2 - 7x + 12
Answer:
x=4
Step-by-step explanation:
"A number" can be rewritten as X:
6x=3x+12
1) subtract 3x on both sides:
3x=12
2) divide both sides by 3:
x=4
Answer:
First option
is the correct answer.
Step-by-step explanation:
Let us consider each part, we have number 6 inside all the roots.
First we have to find cube root of 6.
![\sqrt[3]{6} =6^\frac{1}{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B6%7D%20%3D6%5E%5Cfrac%7B1%7D%7B3%7D)
Now we have to find square root of this value.

So, first option
is the correct answer.
Answer:
step 1. 6x2=12 first place way
step 2. 12×2=24
step 3. 24+6=30 second place way
The formula for volume of a prism is v=(1/2bh)h so it would be
(1/2 ×7.8×4)×9= 140.4
