Answer:
a=-8
Step-by-step explanation:
combine 3a + 3a =6a
so now u ahve 6a =16 +8a
subract 8a from both sides
-2a=16
divide both sides by 2
a=-8
u can plug 8 in to check answer :)
This is a parabolic function
A negative lead coefficient means that f(x) is increasing from the left and decreasing to the right. It will have a maximum value vertex.
<u>Solution-</u>
From the figure,
AE = 2.4
EB = 2.8
BC = 11.7
Area of rectangle 1 = 8.68 sq.in

(∵ sides of the rectangle 2)
Area of Triangle 1 = 6.48 sq.in


(∵ sides of the rectangle 1)


(∵ sides of the rectangle 2)



The area of Rectangle 2,

The area of Triangle 2,

The area of the whole figure = Area of Triangle 1 + Area of rectangle 1 + Area of Triangle 2 + Area of rectangle 2
= 6.48+8.68+8.82+6.44=30.42 sq.in
Are called alternate internal angles.
If the two lines are parallel, the alternate internal angles are congruent.
