Option A
is one way to determine the factors of
by grouping
<em><u>Solution:</u></em>
Factoring by grouping means that you will group terms with common factors before factoring
<em><u>Given expression is:</u></em>

Group the first two terms together and then the last two terms together.

We can see that
is common in first two terms
And 3 is common in last two terms
Factor them out


Thus option A is correct
Answer:
Step-by-step explanation:
4x-8<5x+4
4x<5x+12
-x<12
flip sign
x > -12
The other number is -3.
Step-by-step explanation:
Step 1; First we develop formulae for the given information. A number is added with 3 and the resulting sum is multiplied by 4. This number is then divided by 2 and the quotient is 0. Assume the unknown number is x, then the given information is as follows
The quotient of
is 0. So
= 0.
Step 2; Now we solve the above equation. The denominator is taken to the RHS and the RHS remains zero.
= 0, 4(x+3)= 0, 4x+ 12 = 0, 4x = -12, x =
= -3.
So the other number is -3.
Answer:
94.2
Step-by-step explanation:
i honestly dont know if this answer is right but i am currently takeing classes in math about Geometry. We was learning about Word problems, that had to do with volume, Area, and perimeter, and learned what radius is, etc..
- So i thought you take the formula it gives you and use. Since Pie means 3.14 you use that in the formula. V= 1×3.14×2×15 = 94.2
- you would multiply everything together because every number is close together.
- the height is 15 cm, thats how you get 15 at the end.
- next step is to solve the equation in your calculator. and it gives you that number. = 94.2
