Answer:
26.13
Step-by-step explanation:
Area of the two triangles:
divide by 2 to find the other side of the triangle and the radius
this is just one triangle multiply by two to find both sides together
(6)(2) = 12 this is the area of both triangles
Area of the half-circle:
A =
this is the formula for a whole circle so we have to then divide by 2
=
= 28.3
= 
=
Add the area of the triangle with the area of the half-circle:
12 + 14.13 = 26.13
Hope this helps!!
Answer:
Infinite
Step-by-step explanation:
3(4x + 1) - 2
= 12x + 3 - 2 (Multiply the sum in the bracket by 3)
= 12x + 1 (Simplify)
This means that:
12x + 1 = 3(4x + 1) - 2
is the same as
12x + 1 = 12x + 1
Hence, anything that is used to substitute x is correct.
