Answer:
(2x-7y) (2x+7y)
Step-by-step explanation:
4x^2−49y^2
This is the difference of squares
a^2 - b^2 = (a-b) (a+b)
a^2 =4x^2 so a = 2x
b^2 = 49y^2 so b =7y
4x^2−49y^2 = (2x-7y) (2x+7y)
Answer:I think you are correct
Step-by-step explanation:
We know she got one 100
But we don't know how many 85's she got
So we put x with 85 so (85x) plus the only 100 she got
Leading us too 440
Lmk if u have any questions
Answer c I haven’t done this in awhile but I’m sure it’s c
x-5= 0
move -5 to the other side
sign changes from -5 to +5
x-5+5= 0+5
x= 5
x-6= 0
x-6+6= 0+6
x= 6
Answer: B. 5 and 6
(35+47+42+x)/4 = 50
(35+47+42+x)=4*50
124 +x = 200
x=200 - 124
x= 76
Answer B. 76 points.
