Answer:
156
Step-by-step explanation:
While solving we will have to use the area formula of the rectangle, which is :A=w*l ; length*width=A.
Steps:
1)let’s consider that the shape is a full rectangle. => 16*12=192.
2)9*2=18 -> 18*2=36
3)192-36=156.
Answer:
-69 +92 i (here 'i' is imaginary value)
Step-by-step explanation:
step:-
Given (3-4 i)(-2-21)
on multiplication, we get
(3-4 i)(-2-21) = 3(-2) -3(21) - 4 i (-2) +4 i(21)
= -6 -63 + 8 i +84 i
= -69 +92 i
-69 + 92 i is a complex number.
real part x = -69
imaginary part y = 92

Answer:
B
Step-by-step explanation:
Let the base of the triangle be <em>b</em> and the height be <em>h</em>.
The sum of the base and height is 14. Thus:

Recall that the area of a triangle is given by:

From the first equation, solve for either variable:

Substitute:

Distribute:

Distribute:

Let <em>b</em> = <em>x</em>. Hence:

Therefore, our answer is B.
