Answer:

the coefficient of the 2nd term: - 38

Step-by-step explanation:

V = 2x (4x + 1) (5x - 6)

   =(8x² + 2x) (5x - 6)

   = 40x³ - <u>38</u> x² - 12x

PLEASE HURRY! this is financial algebra
Zina [86]

Answer:

6 years

Step-by-step explanation:

Simple interest= P.R.T

I = $1300

P = 18000 deposit

Rate = 1.19%

T = ?

Putting into the formula we have

1300 = 18000x1.19/100xT

1300 = 18000x0.0119xT

1300 = 214.2T

Divide through to get T

T = 1300/214.2

= 6.069

So when we approximate T = 6 years

It would take 6 years to make $1300 in interest

The length of each side of the square is decreased by 2 inches, so the perimeter is now 48 inches . What was the original length
Jet001 [13]
X=original length of each side of the square.
perimeter: sum of all sides=4(length of the side)
The length of each side of the new square will be= (x-2)
we can suggest this equation:

4(x-2)=48

We solve this equation:
4(x-2)=48
4x-8=48
4x=48+8
4x=56
x=56/4
x=14

Answer: the original length of each side of the square would be 14 in.
