First we have to divide 135,000 by 90, which equals 1,500. Then we divide 1,500 (seconds) by 60 (60 seconds in a minute) and get: 25 Minutes.

IRINA_888 [86]

Answer:

The value will be $3,400 after 3 years

Step-by-step explanation:

Convert the percentage into the cash decrease each year, multiply that by 3 and then subtract $10,000 by the sum.

.22 x 10,000 = 2,200

2,200 x 3 = 6,600

10,000 - 6,600 = 3,400

Which of ghe following is equivalent to (x+4)(3x^2+2x)?

Alexxandr [17]

The given expression is

$(x+4)(3x^2 +2x)$

And in the second factor, x is common. So on taking x out, we will get

$(x+4)(x)(3x+2) = x(x+4)(3x+2)$

We can expand it by distributing , that is

$(x+4)(3x^2 +2x) = x(3x^2 +2x) +4 (3x^2 +2x)$

$= 3x^3 +2x^2 + 12x^2 +8x$

Combining like terms,

$= 3x^3 +14x^2 +8x$

And that's the expanded form ., and the given expression can also be written in that way .
