•
=
⇒ ad = bc, thus
42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides
42w + 462 = 28w + 644 ( subtract 28w from both sides )
14w + 462 = 644 ( subtract 462 from both sides )
14w = 182 ( divide both sides by 14 )
w = 13

Answer:
6x+4y=12
Step-by-step explanation:
when x-intercept is 0
6(0)+4y=12
0+4y=12
divide by 4 both side
y=3
when y-intercept is 0
6x+4(0)=12
6x+0=12
6x=12
divide by 6 both side
x=2
Answer:
An Arc
Step-by-step explanation:
(0,0) and (6,0)

3x²-18x=0
Factor out a 3x
3x(x-6)=0
This means that x is either 0 or 6
Simple,
4x9x2.2 = volume = 79.2 cubic centimeters
79.2/1000 = 0.0792 litres
not sure if you wanted it in cubic or litres FYI if it doesn't say put the answer in cubic :)
