the general equation for velocity in terms of acceleration and displacement is: v² = v₀² + 2ax.
Solve for a: a = (v² - v₀²)/(2x).
You are given v₀ and v, and x is easy to calculate since you are given its initial and final values. The rest is just arithmetic.
(note also: SI expressions have a required space between the coefficient and the unit symbol. Thus you should have things such as “15 m” and “-2 m·sˉ¹” instead of “15m” and “-2m·sˉ¹”.)
5A + 7 = 3A + 7 + 2A
We need to solve for A.
3A + 7 + 2A = 3A + 2A + 7 = 5A + 7 (We can add 3A and 2A because it's the same variable, so we add the coefficients)
5A + 7 = 3A + 7 + 2A
5A + 7 = 5A + 7
5A + 7 is always equal to 5A + 7 because it's the same equation. So the equation got infinitely many solutions.
Answer:
1 1/2
Step-by-step explanation:
one and a half because you have a half leftover and 1 whole
Answer:
Mia is incorrect.
Step-by-step explanation:
She confused the area and perimeter.
Area is length x width, in this case 12 x 5 = 60
Perimeter is length² × width², and in this case, it is 12² × 5² = 34
Area = 60 inches
Perimeter = 34 inches
Hope that helps and have a great day!
