5-16+11i-4i+9i
-11+7i+9i
-11+16i
Step-by-step explanation:
First, get the like terms together. Then add or subtract until its simplified. Simplified is -11+16i.
Answer:
14 in²; D.
Step-by-step explanation:
Hey!
To find the area of a trapezoid, we will add up both of the bases, divide by two, and then multiply the height.
In that case, we'll start by adding up 5 and 9.
5 + 9 = 14
.
7 × 2 (height) = 14.
Thus, the area of the given trapezoid is 
, or D.
Hope this helps!

The volume of the given figure is 210 cubic in..
We need to find the volume of the given figure.
<h3>What is volume?</h3>
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
Divide the given figure into two convenient cuboids. That is one with dimensions length=4 in., breadth=2 in. and height=3 in. Another with length=4 in., breadth=4 in. and height=12 in.
We know that, the volume of cuboid =l×b×h cubic units.
Now, the volume of the cuboid=4×2×3=18 cubic in. and the volume of another
cuboid=4×4×12=192 cubic in.
The volume of the given figure=18+192=210 cubic in.
Therefore, the volume of the given figure is 210 cubic in.

It is given in the question that ,
This week his goal is to bike about 65 total miles over four days. Each day, he wants to ride 1.5 times as far as he rode the day before.
Let, on the first day, he drives x miles. On second day,he drives 1.5x. On the third day, he drives 1.5(1.5x) and on the fourth day, he drives 1.5(1.5(1.5x)).
So we have
So on the first day, he drives 8 miles.
On second day, he drives 8*1.5 =12 miles
On the third day, he drives 12*1.5 = 18 miles
On the fourth day, he drives 18*1.5 = 27 miles
