Answer:
10 + 12 = 24 so she can make 1..
Step-by-step explanation:
This is not an equation and thus cannot be solved for x. Ensure that you have copied down the original problem exactly.
If, on the other hand, you meant x + 2x - 3 + x = - 4, you do have an equation and can solve for x as follows:
4x - 3 = -4 => 4x = -1 => x = -1/4
Answer:
<h2><em>
1.75ft/s²</em></h2>
Step-by-step explanation:
The total change in elevation of the skier is its acceleration. Acceleration is the change in velocity of a body with respect to time.
Acceleration = Velocity/Time
Given velocity of the skier = 14feet/sec
Time taken = 8secs
Acceleration of the skier = 14/8
Acceleration of the skier = 1.75ft/s²
<em>Hence the total change in elevation after 8 seconds is 1.75ft/s²</em>
C = 169
square is (x + 13)^2
Explanation:
In the form:
ax^2+ bx +c
to complete the square a = 1 is required.
c = (b/2)^2
the square term is b/2
x^2 + 26x + c
a = 1 so we are okay to complete the square.
b = 26
c = (26/2)^2 = 13^2 = 169
finally to complete the square:
x^2 + 26x + 169 = (x+b/2)^2 = (x+13)^2
