did you get the answer?? if so please help me out!
Answer:
( a+b) (a-b)
x^2 - 50
Step-by-step explanation:
The formula for difference of squares is
a^2 - b^2 = ( a+b) (a-b)
121x^2 -144 = (11x)^2 - 12^2 so this is the difference of squares
x^2 - 16y^2 = (x)^2 - (4y)^2 so this is the difference of squares
9x^2 -64 = (3x)^2-8^2 so this is the difference of squares
x^2 - 50 = (x)^2 - 2*(5)^2 this is not the difference of squares
Answer:
The answer is 3.
Step-by-step explanation:
-2x + 7 = X-2
-2(3) + 7 = (3)-2
-6 +7 = 1
1 = 1
The answer is C. (I don't know how to type that specific number :/)
Have a good day
Solution:
Given inequality is –7x > 10.
To reduce this inequality to solve for x.
⇒ –7x > 10
Multiply by –1 on both sides of the inequality to reverse the expression.
⇒ –7x × (–1) < 10 × (–1)
⇒ 7x < –10
To simplify the expression, divide by 7 on both sides of the expression.
⇒
⇒
Hence .
