Answer:
31.5 units^2
Step-by-step explanation:
Rectangle area (RA) = l × w
Triangle area (TA) = (bh)/2
RA = 3 × 7
RA = 21
TA = (7 × 3)/2
TA = 21/2
TA = 10.5
(Triangles are congruent as shown by the lines on each side of the triangle so I can calculate area of both of them together as I just did)
Add areas together
21 + 10.5 = 31.5
First multiply 40 and 10 to get 400. Then multiply 400 by 8 to get 3,200.
Your answer would be: 3,200
Answer:

Step-by-step explanation:
We are given that

R=150 ohm
L=5 H
V(t)=10 V





I(0)=0
Substitute t=0


Substitute the values


By asking students to answer un-biased, and with detail. Comparing and contrasting each others' genre preference is also useful.
