Answer:
The side length is approximately 11.3 inches
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
128 = s^2
Take the square root of each side
sqrt(128) = sqrt(s^2)
11.3137085= s
The side length is approximately 11.3 inches
Answer:
I'm pretty sure it's 6(x+8)=60
Step-by-step explanation:
You need to use the distance formula [square root of (x2-x1)^2 + (y2-y1)^2]
square root of (0-(-2))^2 + (-6-4)^2
square root of 2^2 + (-10)^2
square root of 4+100
10.198 so it is 10.2
The answer is true , to find inequalities you have to see which points overlap
Answer:
(5x²+3)(2x-7)
Step-by-step explanation:
As stated, this is a factor by grouping question: a(x+y)+b(x+y)=(x+y)(a+b)
10x³-35x²+6x-21
first, look for common factors.
-35x² and -21 have the common factor of -7
10x³and 6x have the common factor of 2x
now, rearrange the polynomial
10x³+6x-35x²-21
factor 2x out of 10x³+6x
2x(5x²+3)
factor -7 out of -35x² and -21
-7(5x²+3)
Now, the polynomial is 2x(5x²+3)-7(5x²+3)
(5x²+3) is common in both parts, so factor that out, 2x-7 would be another expression as that is left.
now, the expression is
(5x²+3)(2x-7)
Hope this helps!
