Wait I don’t really get it but if you mean the result it is -5x^2 + 5 tho
Answer:
<h2>34.88feet</h2>
Step-by-step explanation:
The set up forms a right angle triangle with the length of the ladder being the hypotenuse and the angle of elevation is 29.32°. USing SOH, CAH TOA to determine the distance of the building from the base of the ladder.
The distance we are looking fir will be the adjacent. According to CAH.
cos29.32°= x/40
x = 40cos29.32°
x = 34.88feet (to the nearest hundredth)
The ladder is 34.88feet away from the building
Answer:
A. 7.5 cm
Step-by-step explanation:
3/4 = (x + 3)/(2x + 1)
3(2x + 1) = 4(x + 3)
6x + 3 = 4x + 12
2x = 9
x = 4.5
BC = x + 3
= 4.5 + 3
= 7.5 cm
Answer:
y=2
Step-by-step explanation:
first solve those in the brackets then find the square root
2y+3=11
put like terms together
3 goes to the right side
2y=11-3
2=8
y=4
√4=2
y=2
