Answer:
W and Y = 91. X and Z = 89
Step-by-step explanation:
Those two angles will add to 180.
5a - 21 + 3a + 25 = 8a + 4
8a + 4 = 180
8a = 176
176 / 8 = 22 = a
Plug in a for an angle.
3(22) + 25 = 91
180 - 91 = 89
Answer:
42x^2
Step-by-step explanation:

1650 - 1200 = 450
What percent is 450 of 1200?
y = 450/1200
y = 0.375
37.5% increase
Answer:


Step-by-step explanation:
for this equation
a=3
b= -5
c = -7
The sum of equal to

and the product is equal to

. All you do is replace the values. You can prove both of those using the quadratic formula.
Hello there!
Make it an equation:
x + x + 2 = -88
2x + 2 = -88
2x = -88 + 2
2x = -86
x = -86/2
x = -43.
The numbers are -43 and -45.
Hope This Helps You!
Good Luck :)
