Answer:
x^2 + 10x + 25; (x + 5)^2.
Step-by-step explanation:
When we're talking about line segments, we just have to find the sum of the two parts of the line segment to find the value of the whole. In this case, we have x^2 + 25, and 10x. So, we add them together.
x^2 + 25 + 10x
= x^2 + 10x + 25
Since this can be immediately factored into (x + 5)^2, you have your answer.
Hope this helps!
1) Add 1.2 to both sides
7k=21
2) Divide 7 on both sides.
k=3
Your answer is 3.
Answer:A
Step-by-step explanation:
-7x^2-4x+20
-(7x^2+4x-20)
-(7x^2+14x-10x-20)
-(7x(x+2)-10(x+2))
-(7x-10)(x+2)
Answer:
70% are propane grills.
Step-by-step explanation:
First, we will find out how many grills are propane. We will add all of the grills that are not propane together.
10 + 5 = 15
And subtract that from the total amount
50 - 15 = 35
Then we will divide the amount of propane grills by the total amount
35 / 50 = 0.7
And multiply that by 100 to get our percentage.
0.7 * 100 = 70
<span> s = -16t^2 + 64t + 3
v = -32t + 64
the maximum height occurs when v = 0:
-32t + 64 = 0 when t = 2 sec
the maximum height is
s = -16(2^2) + 64(2) + 3 = 67 ft
the range is [ 3, 67] </span>
