Answer:
x=2.17
Step-by-step explanation:
+18x+81=-4
-81 -81
+18x= -85
/18 /18
= -4.7
=
x= 2.17
I hope this helps :) (if it does, brainliest, please??)
Answer: x = 70, y = 110, z = 85
Step-by-step explanation:
If BE = CD, then using corresponding angles (are equal), x = 70
If x = 70, then 70+y = 180 (angles on a straight line)
y = 110
And z = 85 (corresponding angles again): angle ABE = angle ACD
Answer:
x=<u>+</u>
Step-by-step explanation:
Quadratic function =( -b<u>+</u> )/2a
x^2+x+2-y=0
x=-1<u>+</u> /2
x=-1<u>+</u> /2
x=<u>+</u>
Pretty sure this is right. Would appreciate a brainliest
