Answer: I believe it is a 90 degree angle.
Answer:
49
Step-by-step explanation:
The expression is given below:
x^2 + 14x
Let y be the constant that will make the expression a perfect square. Therefore, the expression can be written as:
x^2 + 14x + y
Applying the formula b^2 = 4ac, we can easily obtain the value of y as shown below:
x^2 + 14x + y
Coefficient of x^2 (a) = 1
Coefficient of x (b) = 14
Constant (c) = y
b^2 = 4ac
14^2 = 4 x 1 x c
196 = 4c
Divide both side by the coefficient of c i.e 4
c = 196/4
c = 49
Thus, 49 must be added to the expression to make it a perfect square.
If you would like to simplify <span>(-15 + 78) - |22 - 83|, you can do this using the following steps:
</span>(-15 + 78) - |22 - 83| = 63 - <span>|-61| = 63 - 61 = 2
The correct result would be 2.</span>

4) Shade the top left banner
Step-by-step explanation:
Answer:
m - 9 = 3/5 m (Steve has some money. After spending $9, he now has 3/5 of his original amount)
So it's just the matter of isolating m. Subtract m from both sides:
-9 = -2/5 m
Now you just need to multiply both sides by -5/2 to get your final answer.
