15 + x = -7
First, subtract 15 from both sides. / Your problem should look like:
Second, subtract -7 - 15 to get -22. / Your problem should look like:

Answer:
x = -22 (D)
Answer:
3x²(4x-3)
Step by step explanation:
Factorise 12x³-9x²
first, find the HCF of the terms.
the HCF is 3x²
Then you can use the HCF to multiply all terms, each divided by the HCF.
3x²(12x³/3x²-9x²/3x²)
Dividing, we'll have
3x²(4x-3)
7
15
because there are a total of 15 grid and the question asked to pick the grid that doesn't shaded
These solutions can be called “roots”, “zeroes”, and “x-intercepts”.
