Answer: The answer is A, 40.
2 x 2 = 4 + 4 x 4 = 16
4 + 16
= 20 + 2 x 40
20 + 80 = 100
(x = 40)
Answer:
A
Step-by-step explanation:
slope of the given line: -a/b
-4/-2 = 2
realtionship between the slopes of two perpendicular lines:
m = -1/m
slope of the second line
-1/2
line
y-y1 = m(x-x1)
y - 6 = -1/2(x-4)
y = -1/2x + 2 + 6
y = -1/2x +8
The length of the hypotenuse of a right triangle is the square root of (one leg squared plus the other leg squared).
A - area
h - height
a+b - sum of its top and bottom sides
The sum of its top and bottom sides is 8 cm.
