Answer:
m = 6
Step-by-step explanation:
(8m+4) + 38 = 90 ( since they are complementary angles )
8m + 42 = 90
8m = 90 - 42
m = 48/8
m = 6
Answer:
Step-by-step explanation:
-8(1 + 2x) - 2(x+6) = -8 - 16x - 2x - 12
= -18x - 20
Answer:
The perimeter of the polygon is 
Step-by-step explanation:
we know that
The perimeter is the sum of the length sides of the polygon
In this problem
P=XY+YZ+XZ
the formula to calculate the distance between two points is equal to
step 1
Find the distance XY
we have
X(−1, 3), Y(3, 0)
substitute
step 2
Find the distance YZ
we have
Y(3, 0), Z(−1,−2)
substitute
step 3
Find the distance XZ
we have
X(−1, 3), Z(−1,−2)
substitute
step 4
Find the perimeter
P=XY+YZ+XZ

Answer:
Step-by-step explanation:
x²-bx-22=0
put x=4
4²-4b-22=0
16-4b-22=0
-4b-6=0
2b+3=0
b=-3/2
x²-3/2x-22=0
2x²-3x-44=0
2x²-11x+8x-44=0
x(2x-11)-4(2x-11)=0
(2x-11)(x-4)
roots are 11/2,4
Answer:
b = -33/l
Step-by-step explanation:
-1lb + 7 = 40
-1lb = 33 (subtraction property of equality)
-1lb/l = 33/l (division property of equality)
-1b/-1 = -33/l (division property of equality)
b = -33/l (solved)
