Answer:
-14y^2-154y
Step-by-step explanation:
-14y(y+11)
Distribute
-14y*y + -14y*11
-14y^2-154y
In which step did the student first make an error?
Answer: Step 2
Step 2 should be:
−3y = -45 + 6z
Answer:
551.8 feet
Step-by-step explanation:
We are given
Adjacent = 1300 feet
Opposite = x
Angle = 23°
We solve using the trigonometric function Tangent
tan θ = Opposite/Adjacent
tan 23 = x/1300 feet
Cross Multiply
x = tan 23 × 1300 feet
x = 551.81726107 feet
Approximately = 551.8 feet
The Length of the building = 551.8 feet
I think it’s D.y2 +xy+x+3y+2
(Sorry if I’m wrong)
