Answer:
13 and 16
Step-by-step explanation:
The coefficients are the numbers that are next to a variable. In the expression:
13a+16b
Both 13 and 16 are next to a variable. Therefore, 13 and 16 is the correct answer.
Answer:
Area of trapezoid:
12 + 6<-- your two bases of the trapezoid = 18
18 x 4 = 72, 72 divided by 2 = 36
now we multiply by 2 since there are 2 trapezoids:
36 x 2 = 72
Area of rectangle in front:
6 x 3 = 18
Area of the 2 rectangles on the sides:
5 x 3 = 15
(multiply by 2 since there are two rectangles on both sides)
15 x 2 = 30
Area of rectangle on the back:
12 x 3 = 36
Now lets add up all the areas:
72 + 18 + 30 + 36 = 156 in2 is your answer.
Answer:
I'm not sure but I did do it on a calculator so 1.515-1.56= -0.045
56* angles scale regardless of size 90* @ 9mmx9mm is still 90* in 9kmx9km
