Answer:
they are both straight
Step-by-step explanation:
800/$20 per square yard= 40 sq yards
15ft=5 yards
40 sq yds/5 yards= 8 yards or 24 feet
length= 24 feet or 8 yards
A 150% markup of a picture frame that costs 2.99 would cost : 4.49
L*w=area
(3x+21)*w=3x^2+33x+84
w=(3x^2+33x+84)/3x+21
(3(x+4)(x+7))/3(x+7)
w=x+4
The answer is X= 5. Using the pythagorean theorem, and assuming that "b" is 3, half of 6 because the triangle is isosceles, you can solve the problem.
