(7x^2 + 6x + 5 ) - (x - 5)^2
(7x^2 + 6x + 5 ) - (x^2 - 10x + 25)
6x^2 + 16x - 20 is the answer
2nd answer- the angles are not congruent. In order for two figures to be congruent, they have to have the same angles.
56 divided by 7 = 8
48 divided by 6 = 8
8 = 8
since it is the same rate, then
Yes, the truck can travel 48 miles with 6 gallons of fuel
For this case what you should do is find the area of the rectangle and the are of the triangle.
Area of the rectangle:
A1 = (6) * (7)
A1 = 42 in ^ 2
Triangle area:
A2 = (1/2) * (6-3) * (13-7)
A2 = 9 in ^ 2
The total area is the sum of both areas:
A = A1 + A2
A = 42 + 9
A = 51 in ^ 2
Answer
<span> the area of this composite shape is
</span> A = 51 in ^ 2
