Monica wants to measure the dimensions of her rectangular lawn. If the longer side of the lawn is (x + 3) feet and the diagonal
Juliette [100K]
Let us try and solve it analytically. We have that the side=x+3  together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that (x+4)^2=(x+3)^2+s^2. This yields s^2+x^2+6x+9=x^2+8x+16
which yields s^2=2x+7, hence a) is the correct answer.

For which independent value do the equations generate the same dependent value?
nalin [4]

Answer:

x =  - 3

Step-by-step explanation:

The equations given are:

y_1=6x+10

y_2=4x+4

For the equations to generate the same independent value, then

y_1=y_2

This implies that:

6x+10 = 4x + 4

Group similar terms to get:

6x - 4x = 4 - 10

Simplify to get:

2x =   - 6

x =  - 3

Goryan [66]
Pat's fund earned is $526.40 more than Sam's fund.

Sam's investment :
9400*.052 = 488.80*7 = $3,421.60

Pat's investment :
9400*.06 = 564*7= $3,948.00

$3,948.00-$3,421.60=$562.40

The answer to your question is going to be D. $526.40.

Hope this helps you!!:))
