Kameryn types 75 words per minute and is just starting to write a term paper. Joe already has 510 words written and types at a s

AnnZ [28]

Answer:

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

Step-by-step explanation:

Let

x -----> the number of minutes

y ----> the total words typed

we know that

Kameryn

$y=75x$ -----> equation A

Joe

$y=60x+510$ -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for x

$75x=60x+510$

$75x-60x=510$

$15x=510$

$x=34\ minutes$

That means

For x=34 minutes

The amount of words written by Kameryn and Joe are the same.

therefore

For x > 34 minutes

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

Area as a sum: Area as a Product: I need the are as a sum Nd a product

PSYCHO15rus [73]

Given:

The area model.

To find:

The area as a sum and area as a product.

Solution:

The four terms of the area model are $2x^2,10x, 3x, 15$ .

The area as a sum is the sum of all the terms of given area model.

Area as a sum = $2x^2+10x+3x+15$

= $2x^2+13x+15$

The area as a product is the factor form of sum of all the terms of given area model.

Area as a product = $2x^2+10x+3x+15$

= $2x(x+5)+3(x+5)$

= $(x+5)(2x+3)$

Therefore, the area as a sum is $2x^2+13x+15$ and the area as a product is $(x+5)(2x+3)$ .
