-14-2i is the sum of complex numbers
Answer:
remainder = 122
Step-by-step explanation:
Using the remainder theorem to evaluate the remainder
Division by x - 3 , thus evaluate f(3) for remainder
f(3) = 3³ + 14(3)² - 7(3) - 10
= 27 + 126 - 21 - 10
= 122 ← remainder
Answer:
y = -11.5
Step-by-step explanation:
2y = 18-41
Combine like terms
2y = -23
Divide each side by 2
2y/2 = -23/2
y = -11.5

Answer:
C. 84
Step-by-step explanation:
To make it easier to find the total area, you should break the shape into two parts, a triangle and a rectangle.
Step 1:
To find the rectangle area we now we have to multiply <em>l * w</em>
In this case, the length is 12 and the width is 4 so 12*4 = 48
Step 2:
To find the area of the triangle you have to do the formula A = 1/2bh where b is the base 12, and h is the height (10-4) 6. So 6*12 = 72 and 72/2 is 36
Step 3:
Last you need to add the area of both the rectangle and the triangle to get the total area of 84 sq meters
Have a good day!!!
