the last one
x^2+2x+1 R(-5)
There are 6 reading groups
24 students ÷ 4 students each group= 6 reading groups
Well add them all up. : 10+15+8+7=40. There are 8 white balls out of 40. 8/40. Find the GCF of them both and simplify them.
8=8 so 8/8 = 1
40=8 so 40/8 = 5 so 1/5 is your answer.
B. is your answer.
Hoped I helped!
The question is incomplete. Here is the complete question.
m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.
If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.
A. 1
B. 154
C. 77
D. 26
Answer: B. m∠K = 154
Step-by-step explanation: <u>Isosceles</u> <u>trapezoid</u> is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.
Related to internal angles, angles of the base are equal and opposite angles are supplementary.
In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:
18x + 8 = 11x + 15
7x = 7
x = 1
Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:
m∠J = 18(1) + 8
m∠J = 26
m∠K + m∠J = 180
m∠K + 26 = 180
m∠K = 154
The angle m∠K is 154°
