We have that
-7x-60=x²<span>+10x
</span>x²+10x+7x=-60
x²+17x=-60
(x²+17x+8.5²)=-60+8.5²
(x+8.5)²=12.25
(+/-)(x+8.5)=√12.25--------> (+/-)(x+8.5)=3.5
(+)(x+8.5)=3.5------> x=-5
(-)(x+8.5)=3.5------> x=-12
therefore
(x+5)*(x+12) is equivalent to -------> -7x-60=x²+10x
the answer is
(x+5)*(x+12)
8(m+5)=16
8m+40=16
8m=24
m=3
The value of the expression, 5x^2 - 4, when x = 2 is: 16.
<h3>What is the the Value of an Expression?</h3>
To find the value of an expression, plug in the given value of the variable and solve by simplifying.
Given the expression, 5x^2 - 4, when x = 2, we would have:
5(2)^2 - 4
5(4) - 4
20 - 4
= 16
Therefore, the value of the expression, 5x^2 - 4, when x = 2 is: 16.

Answer:
i think 10mph
Step-by-step explanation:
if she ran 100% faster that means she ran double or 200% of the initial speed
deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?
REmember that
The range of a set of data is the difference between the highest and lowest values in the set
If U is the highest value
Range=U-38
range=10
so
10=U-38
U=10+38
U=48
If U is the lowest value
Range=47-U
10=47-U
U=47-10
U=37
therefore
U coulbe between 48 and 37
