Answer:
4 roots
Step-by-step explanation:
Assuming the exuation is
7+(5x^4)- (3x^2)
the polinomial has 4 roots
because a polynomial always has as many roots as it's highest degree
4x + x - 15 + 3 -8x = 13
Combine like terms:
(4x+x-8x) + (-15+3) =13
-3x-12 = 13
+12 +12
———————-
-3x = 25
— —-
-3 -3
X= -25/3
Answer:
I believe the answer is 45.
Step-by-step explanation:
a 90 degree angle is represented by a square on the corner.
So half of 90 is:
90 ÷ 2 = 45
the angle next to the letter M is 90 degreess, so the other side of the line is also 90 degrees.
45 + 90 = 135
and 180 - 135 = 45
(You subtract 135 from 180 since " the sum of angles of a triangle equals the straight angle", which is 180 degrees.
So, the length of JL is equal to 45 degrees.
