If the value of b is 7, then what is the value of the expression -3b^2+25=?
A. 122
B .17
C. 172
D. -122

1.) 8a⁴b³ + 6a²b³ab² - 2a²b³ab

2.) A. 44

3.) B. +83 degrees

4.) D. $0.15

5.) x⁴ - 256

6.) D. -122

7.) -6r²s⁴t³

Step-by-step explanation:

1.) To simplify, we simply multiply/distribute and then combine like terms.

2.) To simplify, we use Order of Operations BPEMDAS to solve.

3.) To find, we simply subtract 68 and -15 to get +83 as our answer.

4.) To find, we simply multiply 3 by 24 to get 72, then divide by $410.80 to get $0.15 as our answer.

5.) To expand/simplify, simply use Difference of Squares to get C. as our answer.

6.) To find the value, simply plug in 7 for b to get -122 as our answer.

7.) To find the result, remember that when you divide exponents, you subtract the powers.
