Answer:
=11x2y3-oxy2+2xy2
Step-by-step explanation:
Simplify:
4x2y3+2xy2-2y-((-7x2)(y3)+oxy2-2y)
Distribute negative sign(-)
=4x2y3+2xy2+-2y+7x2y3+-oxy2+2y
Combine like terms
=(4x2y3+7x2y3)+(-oxy2)+(2xy2)+(-2y+2y)
=11x2y3-oxy2+2xy2
Answer:
y= 550-12x
Step-by-step explanation:
Given data
Content of tank= 550 gallons
Rate of drain= 12gallon per minute
let the time it will take to drain all 550 gallons be x minutes
Hence the expression for amount of water in the tank after x minutes will be
y= 550-12x
Answer:
26, 64
Step-by-step explanation:
we have :
angle 90°
acute angle x
acute angle 2(x+6)
The sum of the angles in a triangle has to be 180° so
90 +x+2(x+6) = 180
90 +x +2x+12 = 180
3x = 180 -90-12
x= 78/3 = 26°
the other acute angle is 2(26+6) = 64°
