Answer:
x = 5.95
Step-by-step explanation:
Given
= 3.5
Multiply both sides by 1.7 to clear the fraction
x = 1.7 × 3.5 = 5.95
Answer:
3
Step-by-step explanation:
There is no x in the equation, so I will assume solving for m
Distribute:
3m + 21 = 6m + 12
Subtract 3m and 12
3m = 9
Divide by 3
m = 3

There are two real roots (5 and -5) and 4 imaginary roots
Answer:
7
cm²
Step-by-step explanation:
First, find the area of the big circle with the formula A =
r²
A =
(3)²
A = 9
Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)
A =
r²
A =
(1)²
A = 
Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:
9
-
-
= 7
So, the area of the shaded region is 7
