Help me find the area of the question c please
Marysya12 [62]

Answer:

16

Step-by-step explanation:

Shape C is A trapezoid

Area of trapezoid = \frac{a+b}{2} h

where a and b =  base lengths and h = height

The trapezoid has the following dimensions

base 1 = 3 units

base 2 = 5 units

height = 4 units

Using these dimensions we plug in the values into the formula stated above.

A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16

Hence the area of shape C = 16 square units

Which of the following systems of inequalities would produce the region
Debora [2.8K]

Answer:

Step-by-step explanation:

Neither blue plot line is dashed, so we eliminate any equation that contains the symbols "<" or ">". Remove A and C

B and D (actually all options) have y ≤ -x + 4 which is a line with slope -1 any y intercept 4. This represents the area below the line running from (0, 4) to (4, 0)

Which leaves us to select from y ≥ x + 2 for option B or y ≤ x + 2 for option D

As the shaded area is <em>below</em> the line we choose <u>option D</u>
