Answer: F
Explanation: you already know you have a 90° and the straight lines means it’s 180° so you need to find x and z which are the same so 2x + 90=180 which you would then subtract 90 from 180 which would be 90 then divide 90 by two which would be 45

Please help I’m confused math is hard!

Answers

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

don't forget to write the original equation first.

V=2(4)(2(4)^2+5(4)+2)

V=8(36+20+2)

V=464 ft^2  

⬆is your answer! hope this helped!!

Answers

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.
