Answer:

L = 16 W=3

Step-by-step explanation:

Let width = x

Length = 4x +4

Area = 48

Area = L times w

48= (4x+4)(x)

48 = 4x^2 +4x

0 = 4x^2 +4x -48

0= 4(x^2 +x-12)

0 = (x+4)(x-3)

x = -4

x=3

Ignore the -4 because it's unrealistic to have negative length width or area

Hence, only solution is 3

Width = 3

Length = 4x + 4 = 4(3) + 4 = 12+4 = 16

Hope this helps!

Please mark brainliest if you think I helped! Would really appreciate!

$1000 earning 5.25% interest compounded annually for 3 years.
Schach [20]

Answer:

$1165.92

Step-by-step explanation:

1000*5.25%=52.5

1000+52.5=1052.5

1052.5*5.25%=55.26

1052.5+55.26=1107.76

1107.76*5.25%=58.16

1107.76+58.16=1165.92

The width is 7 and the diagonal is 25 what is the height
Korvikt [17]
The height is 24.

We can use Pythagorean’s Theorem: a^2+b^2=c^2

substituting values we get:

a^2+7^2=25^2

Solving we get:
a^2+49=625
a^2=576
a=24.

So the height is 24.

Hope this helps!
