Step-by-step explanation:
Answer: I think the length is 60.25 yd and the width is 19.75 yd
Step-by-step explanation: I formed a equation using the information that has been given.
Width : X
length : 1 + 3x
equation : (1 + 3x) + x = 80
Then, I added the like pairs ( 3x+x ). After, I subtracted 1 from 80 and got 79. Then I divided 79 and 4 (79/4) to get 19.75, which is my x value. later, I substituted the x value to the equation and received my answer.

Answer:
10 + (-14) = -4
Step-by-step explanation:
Given that,
Diamond used a number line to add. She started counting at 10, and then she counted until she was on the number −4 on the number line.
For addition, she will add 10 and (-14) as follows :
10 + (-14) = -4
So, the crrect option is (b) "10 + (-14) = -4".
Answer:
In BOLD.
Step-by-step explanation:
f(x) = (x - 1)(x + 7)
Convert to vertex form.
= x^2 + 6x - 7
= (x + 3)^2 - 9 - 7
= (x = 3)^2 - 16
So the vertex is at (-3, -16)
Also, as the vertex is a minimum the graph is increasing on interval x > -3.
From the graph we see:
The graph is positive on the interval
where x < -7 and x > 1.
- and negative where
-7 < x < 1.
