Answer: 66 sq ft
Step-by-step explanation:
Break up the shape into three separate shapes
8 * 3 = 24 for the rectangle
There are 2 triangles
The formula for the area of a triangle is 1/2(b)(h)
1 of the triangles has a base of 4 and height of 12
1/2(4)(12) = 24
The other triangle has a base of 3 and height of 12
1/2(3)(12) = 18
24 + 24+ 18 = 66
Answer:
7.3
Step-by-step explanation:
time is distance divided by velocity/speed
t = 220/30
t = 7.33333 = 7.3
Times 2nd equation by 2
add to first equation
3x+6y=6
<u>4x-6y=8 +</u>
7x+0y=14
7x=14
divide both sides by 7
x=2
sub back
2x-3y=4
2(2)-3y=4
4-3y=4
minus 4 both sideds
-3y=0
y=0
(x,y)
(2,0)
The points on the line are points B and D
<h3>How to determine the points on the line?</h3>
The equation is given as:
y = x + 4
The above means that the output value is 4 more than the input value
Using the above rule, the points that satisfy the equation are:
B) 2, 6 and D) 2, 4
This is so because:
6 = 2 + 4
4 = 2 + 2
Hence, the points on the line are points B and D
