Step-by-step explanation:
Given that,
X = 7x+5
Y = 9x-7
W = 112°
V = 90°
We need to find the measure of each angle. We know that the sum of angles of a quadrilateral is equal to 360°.
7x+5+9x-7+112+90 = 360
x = 10
So,
X = 7x+5 = 7(10)+5 = 75°
Y = 9x-7 = 9(10)-7 = 83°
Answer:
14.49
Step-by-step explanation:
14 * 0.035 = 0.49
14 + 0.49 = 14.49
Multiply both numerator & denominator by 100

If you are using a calculator, simply enter 30÷80×100 which will give you 37.5 as the answer.
Answer: F. (25 − c) ÷ 4
Step-by-step explanation:
Emma had 25 cookies and gave c cookies to her mom and then divided the rest evenly amongst her 4 friends.
The cookies she shared to her friends are the 25 cookies minus the number of cookies she gave her mom which is:
= 25 - c
This (25 - c) was divided by 4 with each portion given to a friend so the total each friend got was:
= (25 - c) / 4
The polynomial will be found as follows;
given that the solution is x=6,x=2 and x=-7, it implies that roots are :
(x-6), (x-2) and (x+7)
Therefore the polynomial will be:
y=(x-6)(x-2)(x+7)
y=x^3-x^2-44x+84
