Hannah just put a 36-foot long
fence around her rectangular
garden. What is the length of the
garden if it is 12 feet wide?

Answers

Answer 1

Answer:

perimeter=sum of all sides

p=2(L+W)

36=2(L+12)

36-24=2L

12=2L

L=6

Answer 2

A rectangle is a 2-D shape with 4 angles. The length of the garden if it is 12 feet wide is 3 feet

How to calculate the perimeter of a rectangle?

A rectangle is a 2-D shape with 4 angles. The formula for calculating the perimeter of a rectangle is expressed as:

P = 2(length + width)

Given

Perimeter = 30 feet

width = 12 ft

Substitute

30 = 2(l + 12)

15 = l + 12

l = 3 feet

Hence the length of thegarden if it is 12 feet wide is 3 feet

Find the zeros of the function f(x)=-1.3x^2-15.7x-44.2 . Round values to the nearest hundredth (if necessary).

Answers

Answer: [tex]-7.60,\ -4.47[/tex]

Step-by-step explanation:

Given

[tex]f(x)=-1.3x^2-15.7x-44.2[/tex]

The solution of the standard quadratic equation [tex]ax^2+bx+c=0[/tex] has solution

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Applying the above principle

[tex]\Rightarrow x=\dfrac{15.7\pm\sqrt{(-15.7)^2-4(-1.3)(-44.2)}}{2(-1.3)}\\\\\Rightarrow x=\dfrac{15.7\pm\sqrt{246.49-229.84}}{-2.6}\\\\\Rightarrow x=\dfrac{15.7\pm \sqrt{16.65}}{-2.6}\\\\\Rightarrow x=\dfrac{15.7\pm 4.08}{-2.6}\\\\\Rightarrow x=-7.60,\ -4.47[/tex]

The zeroes of the equation are -7.60, -4.47.

Answers

Answer:

Step-by-step explanation:

Distribution comes first, so:

7y-9 = 2y-8+1

Then you simplify:

7y-9 = 2y-7

Then you subtract or add the lowest number with a letter:

5y-9 = -7

Now you get 5y alone, so we add the 9:

5y = 2

Then you divide 5y = 2 by 5

y = 2/5 or .4
