Answer: The answer is B.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Required
Solve for A
Simply substitute 18 for b and 30 for h
Hence:
The area is
This can be divided into 2 rectangles. Lets find the dimension of the left rectangle.
40-30=10 so the area of the left is
Now for the one on the right
so
Now lets add the areas
So its 780 feet squared.
Answer:
The height is 9 cm
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
72 = 1/2 ( 16) h
72 = 8h
Divide each side by 8
72/8 = 8h/8
9 = h
The height is 9 cm
Answer:
5x - y = - 2
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
First obtain the equation in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
here m = 5 and the line passes through (0, 2) ⇒ c = 2
y = 5x + 2 ← in slope- intercept form
Subtract y from both sides
0 = 5x - y + 2 ( subtract 2 from both sides )
5x - y = - 2 ← in standard form
