Add '-1' to each side of the equation. 1 + -1 + 3d = 10 + -1 Combine like terms: 1 + -1 = 0 0 + 3d = 10 + -1 3d = 10 + -1                                                                      

Combine like terms: 10 + -1 = 9 3d = 9

Divide each side by '3'. d = 3 Simplifying

Susan Marciano invested part of her 19000 bonus in a fund that paid an 11% profit and invested the rest in stock that suffered a
ioda

The amount invested at 11% is ​$5,000

The amount invested in stock is ​$14,000

What is the net profit on both investments?

The profit of each investment is the rate of return or loss multiplied by the amount invested

Let us assume that x was invested at 11% and the remaining 19000-x was invested at a loss rate of 3%

net profit=(11%*x)+(19000-x)*-3%

net profit=130

130=(11%*x)+(19000-x)*-3%

130=0.11x-570+0.03x

130=0.14x-570

130+570=0.14x

700=0.14x

x=700/0.14

x=$5,000

Amount invested in stock=19000-x

Amount invested in stocks=19000-5000

Amount invested in stocks=$14,000

kykrilka [37]

Answer:

<h2>  The answer is </h2><h2>  D. 8x^2+4xy</h2>

Step-by-step explanation:

We know that the  expression for the perimeter is given as

P=2l+2B

now given that the value of the width is =2x

length= 4x

and the breadth=y

P=4x+2y

let us multiply both the length and the width with 2x we have

P=2x(4x+2y)

P=8x^2+4xy

the answer is

D. 8x^2+4xy
