Answer:
the answer is c because decreased by means the symbol minus so y decreased by 24 will be y-24

Answer: The required polynomial of lowest degree is 
Step-by-step explanation: We are given to find a polynomial function of lowest degree with real coefficients having zeroes of 2 and -5i.
We know that
if x = a is a zero of a real polynomial function p(x), then (x - a) is a factor of the polynomial p(x).
So, according to the given information, (x - 2) and ( x + 5i) are the factors of the given polynomial.
Also, we know that complex zeroes occur in conjugate pairs, so 5i will also be a zero of the given polynomial.
This implies that (x - 5i) is also a factor of the given polynomial.
Therefore, the polynomial of lowest degree (three) with real coefficients having zeroes of 2 and -5i is given by

Thus, the required polynomial of lowest degree is 
Answer:
180 = 90 + 52+ a
38 =a
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
180 = 90 + 52+ a
Combine like terms
180 = 142+a
Subtract 142 from each side
180 -142 = 142+ a -142
38 = a
