When you have an absolute value equation like this, you drop the absolute value signs and change the sign of the value opposite of x.
For instance,
|x| = 3
Let's drop the || signs.
x = 3
This is one solution. Let's change the sign of 3 now.
x = -3
In conclusion,
x = 3, -3
Answer: D and B
Step-by-step explanation:
Formula for two terms = a + b
Therefore,
D and B have two terms aka one plus sign
D. a + c
B. m^4 + 6m
Answer:
The area of the circle is 56.25π cm²
Step-by-step explanation:
- The formula of the circumference of a circle is C = 2πr, where r is the radius of the circle
- The formula of the area of a circle with radius r is A = πr²
<em>To find the area of the circle use the formula of the circumference to find its radius and then use the formula of the area to find its area</em>
∵ The circumference of a circle is 15π centimeters
∵ C = 2πr
- Equate 2πr by 15π
∴ 2πr = 15π
- Divide both sides by π
∴ 2 r = 15
- Divide both sides by 2
∴ r = 7.5 centimeters
Now let us use the rule of the area to find it
∵ A = πr²
∴ A = π(7.5)²
∴ A = 56.25π centimeters²
The area of the circle is 56.25π cm²
