Anew bridge structure requires triangles that are in a ratio of 1: 1. if ac = 4x − 3 and ec = 2x + 6, find the distance between the top and bottom of the bridge, in feet.

4.5 ft
15 ft
18 ft
30 ft

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

homozygous. one is homozygous, while two is heterozygous.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
