Oop yu don’t kno da answerrrrr yu a lil slowwwwwwww 555 wit 10 ?
Answer:
A=246cm
Step-by-step explanation:
L= 9
W= 3
H= 8
2·(3·9+8·9+8·3)= 245
Formula= A=2(wl+hl+hw)
Answer:
y
Step-by-step explanation:
Just use the formula...,
; y - y(coordinate) = slope × [ x - x(coordinate)]
; where we firstly have to calculate the slope...,
; (8 - 2)/(4 - 6) = -3
Then substitute into the formula using point(4, 8)...and you can also use the other point if you wish to
; y - 8 = (-3)(x - 4)
; y - 8 = -3x + 12
Hence the equation of the line....,
; y = -3x + 20
Answer:
16 minutes
Step-by-step explanation:
Because the tank already holds 5 gallons of water, you only need to find the number of minutes to fill 4 gallons of water.
Because it fills at a rate of 1/4 gallons a minute, it takes 4 minutes per gallon of water.
Since we are dealing with 4 gallons of water to be filled, we multiply 4 · 4 to get the number of minutes.
4 · 4 = 16
16 minutes
Remember that the formula for the perimeter of a rectangle is:
is the width of the rectangle
is the length of the rectangle
Thus, in this case, you can see that we are adding two of the same monomials and two of another monomial. One monomial is 
and another monomial is 
. In this case, these monomials would fulfill the perimeter equation of a rectangle.
Applying this perimeter structure, we can find that this expression represents a perimeter equation of a rectangle with sides x + 15 and x + 5.
