Answer:
A.
B.
Step-by-step explanation:
A. The area of the shaded region = area of the whole large square - area of the 4 smaller squares
= (5x*5x) - 4(4*4)
Area of shaded region =
B. The expression, , is the difference of two perfect squares, 25x² and 64. Therefore, apply the rule of factoring difference of two perfect squares.
Thus,
Therefore, the expression of the are of the shaded region can be expressed in factored form as:
Answer:
Step-by-step explanation:
f(x) + n - shift the grapf n units up
f(x) - n - shift the grapf n units down
f(x + n) - shift the grapf n units to the left
f(x - n) - shift the grapf n units to the right
-f(x) - reflection about the x-axis
f(-x) - reflection about the y-axis
============================================
Look at the picture.
move the graph 2 units to the right and 1 unit up
move the graph 4 units down
reflection the graph about the X axis.
Answer:
16:36 = 32:72 = 12:27
Step-by-step explanation:
An easy way for me to solve this is to divide the first value by the second. If they turn out to be the same fraction, then they are equivalent.
Is 16:36 = 32:72?
Yes, because
Is 16:36 = 12:27?
Yes, because
Is 16:36 = 3:4?
No because
