Answer:1.41
Step-by-step explanation: subtraction

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)
Answer:
D. -1/64
Step-by-step explanation:
F(x) = (1/4)^-3
This is 1/4 to the power of -3
= -(1/4)*(-1/4)*(-1/4)
= -(1*1*1)/(4*4*4)
= -1/64
Another way to calculate this is (-1/4)*(-1/4)*(-1/4). This is the same as (-1/4)³
When solved out the solution = -1/64
Therefore the correct answer to this question is the last option, which is d.
Thank you.
This is easy, make 80% of 60 first which is 48, then make 75 percent of 48 which is 36 I believe.
I never do this, but may I please have Brainliest?
Answer:
a
Step-by-step explanation:
2x^2-4x 6x^2-5x
2x^2 times 6x^2= 12x^4
2x^2 times -5x= -10x^3
-4x times 6x^2= -24x^3
-4x times -5x= 20x^2
12x^4-10x^3-24x^3+20x^2
12x^4-34x^3+20x^2
(Also Brainliest if this helps pls)
