Answer:

(5a^2-4)(25a^4 + 20a^2+16)

Step-by-step explanation:

125a^6-64

WE can write 125 as 5^3

Also a^6 = (a^2)^3

64  can be written as 4^3

125a^6-64

5^3(a^2)^3-4^3

(5a^2)^3-4^3

Now we apply a^3 - b^3 formula

a^3 - b^3 = (a-b)(a^2 + ab+b^2)

a= 5a^2  and b = 4

Plug in the values in the formula

(5a^2)^3 - (4)^3 = (5a^2-4)((5a^2)^2 + (5a^2)(4)+4^2)

= (5a^2-4)(25a^4 + 20a^2+16)

WE factored it completely

Tom and Jerry both earn the same monthly salary.
Nata [24]

Answer: Jerry saves more

Step-by-step explanation: first make up the number they make each month to make it easy ill go with 5. so tom saves 35% of 5 dollars each month

35% of 5 is 1.75. So tom saves 1.75 dollars

If Jerry spends 3/5 of his money then he saves 2/5 of his money

2/5 of 5 is 2

Jerry saves 2 dollars each month and Tom saves 1.75 so Jerry saves more

hope this helps mark me brainliest if you can

Answer:

For the cylinder shown in picture:

Perimeter of base = 2 x pi x radius = 2 x pi x 9 = 18pi

=> The area of label = perimeter of base x height = 18pi x 13 = 234pi =~735.1

Area of base = pi x radius^2 = pi x 9^2 = 81pi

=> The surface area of cylinder

S = base area x 2 + area of label = 81pi x 2 + 234pi = 396pi =~1244.1

Hope this helps!

Can you help me solve this

2 times the length of the midsegment equals the length of the base. That being said, your equation will be 2(x+21)=x+32.

First, use the distributive property on 2(x+21). You are left with 2x+42=x+32.
Subtract x from both sides. You are left with x+42=32.

Finally, subtract 42 from both sides of the equation. You are left with your answer: x=-10.

Check your work: -10+21=11 and -10+32=22
11 is half of 22.
