A = (a + b)/2 * h
4 = (a + b)/2
(a + b) = 8
(1+7), (2+6), (3+5), (4+4)
Therefore there are 4 possibilities.
Answer: 16a +8
Step-by-step explanation:
Put g(a) in f(a) in place of a l;ike this:
4(4a + 3) -4 =16a + 12 - 4 = 16a + 8
Formula- A = π r²
a= area
r= radius
diameter of the circle- 3.75 x 2 = 7.5
hope this helps :)
Answer:
Does exist -- It only exists when the determinant does not equal zero.
Step-by-step explanation:
The inverse of a matrix is the transpose of the cofactor matrix, divided by the determinant. If the determinant is zero, the result of the division is undefined and the inverse does not exist.
__
For this matrix, the determinant is (-2)(18) -(9)(4) = -72. The inverse exists.
