Answer: $801

Step-by-step explanation:

to find the slope, you can divide 445÷5=89. (now we know that the rate is $89/1 month)

to find the cost of 9 months, multiply 89•9=801

so since it's asking the cost after 9 months, i think the answer should be $801.

Simplify the sum. (4u3 + 4u2 + 2) + (6u3 – 2u + 8)

Elan Coil [88]

Answer:

$10u^{3}+4u^{2}-2u+10$ or $2(5u^{3}+2u^{2}-u+5)$

Step-by-step explanation:

we have

$(4u^{3}+4u^{2} +2)+(6u^{3}-2u+8)$

step 1

Group terms that contain the same variable

$(4u^{3}+6u^{3})+(4u^{2})+(-2u)+(2+8)$

step 2

Combine like terms

$(10u^{3})+(4u^{2})+(-2u)+(10)$

step 3

Eliminate parenthesis

$10u^{3}+4u^{2}-2u+10$

step 4

Factor the number $2$

$2(5u^{3}+2u^{2}-u+5)$

Answer:

90428160.3 ft³

Step-by-step explanation:

The question is on volume of a pyramid with a square base

The formulae for volume of a pyramid is V=( l×w×h)/3

where l is length of pyramid base, w is width of pyramid base and h is the height of the pyramid

The pyramid has a square base thus l=w= 751 feet

The height of the pyramid is h=481 feet

v= (751×751×481)/3

v=90428160.3 ft³
