They arent equivalent because the simplified version of 3(5x) is 15x and the simplified version of the other one is 45x.

Hope this helps!!

Well, let’s start with simplifying both of them. 3(5x) simplifies down to 15x. For (3*5)(3*x), you have to use FOIL. Using FOIL you get 9+3x+15+5x, which by combining like terms you get 8x+24. These are clearly not equal (equivalent). You can explain that solving them produces different results and give the process I used to solve both of them.

HELP PLEASE I BEG
OverLord2011 [107]

Answer:

Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.

Step-by-step explanation:

Given that Juan invested $ 19000 in two mutual funds, and Fund A earned 7% profit during the first year, while Fund B earned 3% interest, if he received a total of $ 1042 profit, to determine how much she had invested in each mutual fund the following calculation must be performed:

19000 x 0.07 + 0 x 0.03 = 1330

15000 x 0.07 + 4000 x 0.03 = 1170

11000 x 0.07 + 8000 x 0.03 = 1010

11500 x 0.07 + 7500 x 0.03 = 1030

11800 x 0.07 + 7200 x 0.03 = 1042

Therefore, Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.

Answer:

Part 1) The volume of the storage body is 576 cubic feet

Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

Part 3) Sheila can fit 64 boxes into the truck

Step-by-step explanation:

step 1

Find the volume of the storage body

we know that

The volume of the of the storage body is equal to the volume of two rectangular prism

The volume of a rectangular prism is equal to

V=LWH

First rectangular prism (top)

V=(15)(6)(8-6)=180\ ft^3

Second rectangular prism (bottom)

V=(15-4)(6)(6)=396\ ft^3

The volume of the storage body is

V=180+396=576\ ft^3

step 2

we know that

To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

step 3

substitute the given values

\frac{576}{9}= 64\ boxes

therefore

Sheila can fit 64 boxes into the truck
