Alright, so plugging it in, we get 2(-4)^2=2(2)^4+3^2-(-4)^2+2^4. Use PEMDAS with parenthesis and exponents to then get (2)(16)+9-16+16. Multiplying 1 and 16, we get 32+41-16+16=73

Step 1: Distribute the subtraction sign to all the numbers in the second set of parentheses...
Step 2: Combine like terms (
's go with 's)
Step 3: Combine like terms (
's go with 's)
Step 4: Combine like terms (normal numbers go with normal numbers)
1 + 2

You were correct!

I don't really know how to explain this one but I got: (7m-6n)(7m-6n)
Answer:
Step-by-step explanation:
let x be the number.
9x+16≥-26
9x≥-26-16
9x≥-42
3x≥-14
x≥-14/3
Answer: A
Step-by-step explanation:
On a reflection through the x-axis, the x-coordinate of the point will not change, but the y-coordinate will be changed with a negative sign.
So, the reflection of the point is: (8, -7)
Therefore, Option(a)(8, -7) is true.
Answer:14
Step-by-step explanation:
The largest Prime factor of 35 is 7 (factors of 35 are 1,5,7,35)
the smallest prime factor of 12 is 2 (factors of 12 are 1,2,3,4,6,12)- and 1 is not Prime
7*2=14
