Answer:
22x^2-9x+32
Step-by-step explanation:
(21x² - 6x +14) + (x²-3x+18)
To add, we need to combine like terms
21x^2+x^2 -6x-3x +14+18
22x^2-9x+32
The answer is C. 14.6.
By evaluate, they mean substitute in the values of x and y to find the total of the expression, so you get:
(3^2 + 4^3)/(3 + 2) = (9 + 64)/5 = 73/5 = 14.6
I hope this helps!
Answer:I believe it is 31 degrees
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
I think there may be other ways to do this ... but this is one I guess....
one angle= 90 ( given)
the other = 45 (given)
the third = 90 + 45 + a = 180
(all angles of triangles is 180 [angle sum property])
a = 180 - 135
= 45
The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so
if one side is 7
the x is 7 too
(as it cant be the hypothenus)
I think this is right
