B = √(14² - 9²) = √(196-81) = √115 ≈ 10.7 units
Answer:
7500
Step-by-step explanation:
because 4x+20y=-36,so ( 4x+20y)/2=2x+10y=-18
(2x+10y)-(2x+5y)=-18-18
5y=-36
then y=-7.2
because 2x=18-5y
so x=(18-5y)/2=(18-5*(-7.2)）/2=27
Answer:
2260 in^2
Step-by-step explanation:
scaled basically means multiplied by
so 226 times 10 is 2260
dont forget your units or you will get it wrong
The main formula is E = sum Work,
or the work is W= FxAB=E
so AB= E/F = 126/ 14 = 9m
