Answer:

8units²

Step-by-step explanation:

Area of the trapezoid = 1/2(a+b)h

a and b are the opposite sides

h is the height

Take a square as 1 unit

a = 1 unit

b = 3 units

height h = 4 units

Substitute

A = 1/2(1+3)*4

A = 1/2 * 4 * 4

A = 16/2

A = 8units²

Hence the area of the trapezoid is 8units²

An infinite number of ratios are equivalent to 3:8. How
can that be possible, when the multiplication table only

Answers

Answer:

See below, please!

Step-by-step explanation:

There are infinite number of ratios equivalent to 3:8 because both numbers can be multiplied by a common number or divided by a common number.

For example, 9:24 would still be equivalent to 3:8 because the common number in our case is 3. See what I mean?

3x + 1/3y=12
2y=18x+72

Show all work

A no solution
B one solution
C infinity solutions

Answers

Answer:

B one solution

Step-by-step explanation:

3x + 1/3y=12

2y=18x+72; y = 18x/2 +72/2; y =9x+36

3x + 1/3y=12

multiply all through by 3

9x + y = 36

9x + 9x+36 = 36

18x =36-36= 0

x= 0/18 = 0

y =9x+36

y = 9(0) +36 = 0+36= 36
