1 answer:
Answer:
a)
b)
Step-by-step explanation:
Recall the forms of vertical and horizontal lines
Horizontal lines come in the form of , so the slope of the equation is zero. The value of b will be the y-value of the point that you're given.
This means that the equation for a would be y=1
Vertical lines come in the form of . For this line, the value of a would be equivalent to the x-value of the given point. Therefore, b. would be

Answer:
number one. 186 number two. 36
Step-by-step explanation:
FOR NUMBER ONE:
the area of a trapezoid formula is where a and b are the bases and h is the height. so we have to add in the numbers into the formula
= <em>81</em>
and the paralellogram formula is b×h. where b is the base and h is height
15 × 7 = <em>105</em>
so the area of the figure is 81 + 105 is 186 in^2
FOR NUMBER TWO:
the area of the square formula is . where s is the side
4^2 = <em>16</em>
and for the paralellogram is b × h
4 × 5 = <em>20</em>
so the area of the figure is 16 +20 = 36 in^2
hope this helps! ;)
