Answer:
(a + 9)(a - 5)
Step-by-step explanation:
Given
a² + 4a - 45
Consider the factors of the constant term (- 45) which sum to give the coefficient of the a- term (+ 4)
The factors are + 9 and - 5 , since
9 × - 5 = - 45 and 9 - 5 = 4 , then
a² + 4a - 45 = (a + 9)(a - 5) ← in factored form
Answer:
the triangle is translated 2 units up, and is reflected across the x axis
Step-by-step explanation:
G = 4n is the correct equation to use. Eg 10 x 4 = 40, 18 x 4 = 72 and 21 x 4 = 84
The answer is -9 + 9i. Hope this helped.
Answer:
1) A = 547.1136, C = 82.896
2) A = 678.5226, C = 92.316
3) A = 844.5344, C = 102.992
4) A = 1554.49625, C = 139.73
5) A = 1561.4906, C = 140.044
6) A = 994.8776, C = 111.784
