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
(-5)(10)= 50 degrees

Answer:
875 ft²
Step-by-step explanation:
Finding area of similar rectangles:
Scale factor = EF : AB
= 25 : 5
= 5 : 1
Area or rectangle EFGH = 875 ft²
Answer: I think b
Step-by-step explanation:
Answer:
multiply the whole equation by -1
Step-by-step explanation:
it would look like
-1(–ab + bc + ca)
negatives multiplied make a positive and a negative and positive multiplied makes a negative so the end result is
ab – bc - ca
