She can make three shirts and will have 7/56 left.
Step-by-step explanation:
49/56-14/56=35/56 (one shirt) 35/56-14/56=21/56 (two shirts) 21/56-14/56=7/56 (three shirts)
The partial factorization of x2 – x – 12 is modeled with algebra tiles.
An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled + x, 3 are labeled +. 1 tile is in the Factor 2 spot and is labeled + x. 20 tiles are in the Product spot: 1 is labeled + x squared, 3 are labeled + x, the 4 tiles below + x squared are labeled negative x, and the 12 tiles below the + x tiles are labeled negative.
Which unit tiles are needed to complete the factorization?
Answers
Answer:
x² – x – 12 = (x – 4)(x + 3)
Step-by-step explanation:
Identify two numbers that add to -1 and multiply to -12, let's call them p and q.
So ax² + bx + c = (x + p)(x + q)
pq = c
p + q = b.
It is easier to find these numbers by finding factors of -12.
This can be done by splitting the number up until all the numbers are prime.
-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)
There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.
We can eliminate them by adding them up.
6 + -2 = 4 ≠ -1 so that can't be it.
-6 + 2 = -4 ≠ -1 so that can't be it either.
-3 + 4 = 1 ≠ -1
therefore p and q are 3 and -4 because 3 + -4 = -1.
so x² – x – 12 = (x – 4)(x + 3)
p = -4, and q = 3.
(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

Factorise fully 6x² - 15x
Answers
Answer:
3x(2x - 5)
Step-by-step explanation:
because you have x² that means that you have to timse x by x to get x².
6 divided by 15 gets you a decimal but both number goes into the 3 times table
Therefor 6x² - 15x = 3x(2x-5)
If you need to check just times 2x by 3x which would get you 6x² and 5 by 3x which would get you 15x

Answers
Answer:
A
Step-by-step explanation:
Given
6x + 2 - 8x + 7 = 4x + 1 ← simplify left side
9 - 2x = 4x + 1 ( subtract 4x from both sides )
9 - 6x = 1 ( subtract 9 from both sides )
- 6x = - 8 ( divide both sides by - 6 )
x = [tex]\frac{-8}{-6}[/tex] = [tex]\frac{4}{3}[/tex] → A

What is 8q+12=4(3+3q)
Answers
Answer:
q = 0
Step-by-step explanation:
8q + 12 = 4( 3 + 3q )
Distributive property
8q + 12 = 4 ( 3 + 3q )
8q + 12 = 12 + 12q
Inverse operations
8q + 12 = 12 + 12q
-8q -8q
12 = 12 + 4q
-12 -12
0 = q
q = 0
Answer:
Q = 0
Step-by-step explanation:
1. Expand.
8q + 12 = 12 + 12q
2.cancle 12 on both sides.
8q = 12q
3. Move all terms to one side.
8q - 12q = 0
4. simplify 8q - 12q to -4q.
-4q = 0
5. Divide both sides by -4.
q=0
therefor, the answer is q=0
