Brums [2.3K]

Answer:

Length is 3 meters and the Width is 5 meters

Step-by-step explanation:

L*W=15

L=2W-7

(2W-7)W=15

2W^{2} -7W=15\\2W^{2} -7W-15=0

(2W+3)(W-5)=0, don't use (2W+3)=0, because it gives you a negative dimension.

W=5, L=3

Joan has earned grades of 88, 94, 92, and 98 on math tests so far. What must her next grade be to give her an average grade of 6
Ira Lisetskai [31]

Answer:

see the explanation

Step-by-step explanation:

Let

x ------> the next grade

we know that

To find the average grade sum the grades by the number of math test

so

60=\frac{(88+94+92+98+x)}{5}

solve for x

Combine liker terms in the right side  

60=\frac{(372+x)}{5}

Multiply by 5 both sides

300=372+x

Subtract 372 both sides

300=372+x

x=-72 -----> this is not make sense

The grade cannot be a negative number

so

For x=0

The minimum average grade is

\frac{(372)}{5}=74.4

If two integers are positive, the one closer to zero is_________greater
finlep [7]

Answer:  C) Never

If two integers are positive, the one closer to zero is <u>  never  </u> greater.

An example would be something like the integers 3 and 5. The value 3 is closer to zero, so it's not greater than 5. Stuff on the left is smaller than stuff on the right.
