Step-by-step explanation:
length = (2x + 3) units
width = (x - 7) units
Area = 2( length × width)
Area = 2( (2x + 3) × (x - 7) )
Area = 2( 2x² - 14x + 3x - 21)
Area = 2 ( 2x² -11x - 21)
Area = 4x² - 22x - 42
Answer:f=-1
Step-by-step explanation:
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line
m = 
= 
=
Answer:
Statement: Reason:
ΔNQM and ΔNQP are right triangle Definition of a right triangle
SinM = h/p and SinP = h/m Definition of sine ratio
p sin M = m sin P Substitution property of equality
p sin M / pm = msinP / pm Division property of equality.
Answer:
False
