Answer:
The answer is -12
Step-by-step explanation:
2xy + 3x + 4x + 3 if x = 5 and y = -5
Now,
2xy + 3x + 4x + 3
2(5)(-5) + 3(5) + 4(5) + 3
-50 + 15 + 20 + 3
38 - 50 = -12
Thus, The answer is -12

Answer:
Rachel is correct
Step-by-step explanation:
We can calculate angle T by using cosine rule where;
t² = r² + m² - 2rm cos T
From the diagram, we see that;
t = 30
r = 18
m = 24
Thus;
30² = 18² + 24² - 2(18 × 24)cosT
900 = 324 + 576 - 864cosT
864cosT = 900 - 324 - 576
864cosT = 0
cosT = 0/864
T = cos^(-1) 0
T = 90°
