6 0

Using formula of difference of two squares a^2 -b^2 =(a-b)(a+b) we get

49p^2 -64y^2 = (7p -8y)(7p +8y)

and

1 - 25x^2 = (1 -5x)(1 +5x)

Answer:

b=2r+4

Step-by-step explanation:

I don't think that you can do this using only one variable because there are two unknown amounts. Blue (b) is Red (r) multiplied by 2 plus 4 more, so the expression is b=2r+4.

An ant looks up to the top of a building at an angle of elevation of 32°. Then, the ant walks an additional 88 feet from the edg

mel-nik [20]

Measure of the angle that is opposite the line of 88 feet:
180° - ( 22° + 148° ) = 10°
Using the Sine Law:
sin 10° / 88 = sin 22° / x
0.173648 / 88 = 0.3746 / x
x · 0.173648 = 88 · 0.3746
x = 189.84 ft
h - height of a building:
h / x = sin 32°
h = x · sin 32° = 189.84 · 0.529919 = 100.59987 ≈ 100.6 ft
Answer: A ) 100.6 feet
