Komok [63]

Answer:

Length = 6.25 feet

Step-by-step explanation:

Your dad is designing a new garden for your backyard. He has 20 feet of fencing to go around the garden.

Let the width is x.

Length is 2 1/2 feet longer than the width i.e. (x+2 1/2) = (x+2.5) feet

Perimeter = 20 feet

2(l+b) = 20

(l+b) = 10

(x+2.5+x) = 10

2x+2.5 = 10

2x = 7.5

x = 3.75 feet

Length = (x+2.5)

= (3.75+2.5)

= 6.25 feet

So, the length of the garden is 6.25 feet.

gabriel saves 40% of his monthly paycheck for collage. he earned $270 last month.how much money did gabriel save for collage
rusak2 [61]
The best thing to do is to find 10%, and you can do this by dividing $270 by 10, and therefore, $27 is equal to 10%. To find 40%, you've got to multiply $27 by 4, and this gives you $108. Therefore, gabriel saved $108 last month :)

Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)?<br> Help
Alisiya [41]

Answer:

h(4) = 0

Step-by-step explanation:

Hoping its ' kx '

h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k

Now we have k = -2. We will find h(4).

h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0
