Answer:
Step-by-step explanation:
Get the perimeter of the each shape and add it all up to get the total fencing material required.
2 square flower beds = 2 x 4a = 8a
1 rectangular play ground = 2l + 2w
total fencing material = 8a + 2l + 2w
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
Answer:
(x+6)^2 =0
Step-by-step explanation:
x^2+ 12x + 36 = 0
Subtract 36 from each side
x^2+ 12x + 36-36 = 0-36
x^2 +12x = -36
Take the coefficient of x
12
Divide by 2
12/2 =6
Square it
6^2 =36
Add this to each side
x^2+ 12x + 36 = -36+36
(x+12/2)^2 = 0
(x+6)^2 =0
The slope is 1
Difference between the first and second y is 8
Difference between the first and second x is also 8
(8,8) simplifies to 1

Explanation:
First, you had to do is remove parenthesis.
And then, subtract by the numbers. Subtract it's going to be subtract by the numbers, fractions, and find the difference between the numbers.
Hope this helps!
