Answer:
(x−2)(x−4)
Step-by-step explanation:
Let's factor x2−6x+8
x2−6x+8
The middle number is -6 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -6
Multiply together to get 8
Can you think of the two numbers?
Try -2 and -4:
-2+-4 = -6
-2*-4 = 8
Fill in the blanks in
(x+_)(x+_)
with -2 and -4 to get...
(x-2)(x-4)
Hope this helps! Also, if it's no trouble, can I have brainliest? Thanks! :D
Answer:
k = +10 or -10
Step-by-step explanation:
It's given in the question that the roots of the eqn. are real and equal. So , the discriminant of the eqn. should be equal to 0.
Here are 5 ordered pairs (0,5) (1,3) (2,1) (3, -1) (4, -3)
The slope is -2 of c. You always call the y intercept b and the slope m.
Based on the perimeter solved, the length and width of the rectangle will be 11.34 feet and 4.67 feet respectively.
<h3>How to solve the perimeter</h3>
Width = w
Length = 2w + 2
Perimeter = 2(Length + Width)
Perimeter = 2(Length + Width)
32 = 2(2w + 2 + w)
32 = 4w + 4 + 2w
32 - 4 = 6w
28 = 6w
w = 28/6 = 4.67
Length = 2w + 2 = (2 × 4.67) + 2 = 11.34
