Answer: HI!
Step-by-step explanation:
The GCF is 7.
Therefore, divide both denominator and numerator by 7.
<u>21 ÷ 7</u>
56 ÷ 7
= 3/8
Answer:
4+36x
Process:
4(1+9x)
Multiply 4 by the parentheses
=4*1+4*9x
=4+36x
I hope this helped! If it did, a brainliest would be much appreciated :)
Use the Difference of Two Squares Formula,
If x² = 4x², then x = √4x², x = 2x
If y² = 49, then y = √49, y = 7
We know both x and y, straight to formula.
Therefore, the factored form of 4x²-49 is (2x+7)(2x-7)
