Answer:
a=6 or -6
Step-by-step explanation:

(a-6)(a+6)=0
a=6 or -6
Answer:
<h2>132.25π m²</h2>
Step-by-step explanation:
The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.
then
by equating the last two expressions we get: 23π = 2πr then r = 23/2
then
the area = π × r² = (23/2)²×π = (132.25)×π
Answer:(-3,-8),(-6,4),(1,-1)
Step-by-step explanation:
Given
Vertices of the triangle are

Coordinates (a,b) when reflected about x-axis is given as (a,-b) i.e. Y coordinate changes its sign

<span>4y-9=15
Add 9 to both sides.
4y = 24
Divide both sides by 4.
y = 6
The value of y is 6.</span>
