A = -2 and b = -3, evaluate a(a² + b²)

-26

Step-by-step explanation:

a = -2 and b = -3, evaluate a(a² + b²)

= -2(-2²+-3²)

= -2(4+9)

= -2(13)

= -26

-26

Step-by-step explanation:

Concept:

When encountering questions that gave you numbers that stand for each variable and require an evaluation, it is basically substituting the numbers back to the given expression.

Solve:

a = -2, b = -3

Given

a (a² + b²)

Substitute numbers

=(-2) [(-2)² + (-3)²]

Simplify exponents inside the bracket

=(-2) [ 4 + 9]

Addition inside the bracket

=(-2) [13]

Simplify through multiplication

=-26

Hope this helps!! :)

Please let me know if you have any questions

(

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
