Simplify each expression using Order of Operations. a. 2(3 + 4) + 3 to the 3rd power
b. 5 + (3 to the 2nd power - 2 to the 2nd power)

a) 4,913

b) 10

Step-by-step explanation:

a) [2(3 + 4) + 3]³

= [2(7) + 3]³

= (14 + 3)³

= 17³

= 4913

b) 5 + (3² - 2²)

= 5 + (9 - 4)

= 5 + 5

= 10

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
