Answer:
no solutions
Step-by-step explanation:
−4x+5=−4x−5
Add 4x to each side
−4x+4x+5=−4x+4x−5
5 = -5
This is never true, so there are no solutions
Answer:
32, 28
Step-by-step explanation:
3x^2 + 5
= 3(3)^2 + 5
= 27 + 5
= 32
x + 25
= 3 + 25
= 28
Answer:
Option B.
Step-by-step explanation:
step 1
Find the central angle of the shaded sector
Remember that the diameter divide the circle into two equal parts ( 180 degrees each part)
so
Let
x -----> the measure of the central angle of the shaded sector
∠x+72°=180°
∠x=180°-72°=108°
step 2
Find the area of the circle
The area of the circle is
we have
assume
substitute
step 3
Find the area of the shaded sector
Remember that the area of the complete circle subtends a central angle of 360 degrees
so
by proportion find the area of a sector by a central angle of 108 degrees
