Answer:
12 + 2x
Step-by-step explanation:
<em>simplifying</em><em> </em><em>expression</em><em>:</em>
2(10) + 2(x-4)
2 × 10 = 20
2 × x = 2x
2 × -4 = -8
20 + 2x - 8
20 - 8 = 12
12 + 2x
<em>if you want to simplify it</em><em> </em><em>more</em><em>:</em>
(12/2) + (2x/2)
2(6 + x)
<em>if you want to solve for x:</em>
12 + 2x = 0
(12 - 12) + 2x = (0 - 12)
2x/2 = -12/2
x = -6
hope this helps you!
Factor the equation into...
(3b+5)(3b+5)=0
Each factor 3b+5=0 so 3b=-5 so b=-5/3
Check:
9(-5/3)^2+30(-5/3)+25=
9(25/9)-50+25=
25-50+25=0
It checks,
So answer is A.-5/3
Answer:
-60 + - 85 + -115 = -260
if this is not what you asked im so sorry please comment and you can remove this if it is wrong
Keesha would say the ball is traveling at 7 km/h. The correct option is the second option 7 km/h
<h3>What is relative velocity? </h3>
<em>Relative velocity </em>is defined as the velocity of an object with respect to another observer.
From the question, we are to determine how fast Keesha would say the ball is traveling. That is, the relative velocity
Relative velocity of the ball = 12 km/h - 5 km/h
Relative velocity of the ball = 7 km/h
Hence, Keesha would say the ball is traveling at 7 km/h. The correct option is the second option 7 km/h
