Split it up into 3 separate shapes.
Rectangle 1 = 15 x 3 = 45
Rectangle 2 = 3 x 5 = 15
Triangle = 1/2 x 5 x 3 = 7.5
Total area = 45 + 15 + 7.5 = 67.5 cm²
Hey Katie
4^2x+3 = 1
We need to solve for x
log(4^2x+3) = log (1)
Now take log of
(2x +3) * log (4) = log (1)
2x + 3 = log(1)/log(4)
2x + 3 = 0
2x = 0 - 3
2x = -3
x = -3/2
I hope that's help !
Answer:
A line is an infinite two dimensional figure
so yull do math I'm guna do different number just plug these in for.your numbers 225/(375+x)=25
cross multiply land solve900-375 x=525 then cheak
225/(375+525) = .25
(%)(V1)+(%)(V2-V1)=(%)(V2)
(0.70)(x)+(0.30)(600mL-x)=(0.55)(600)
(0.70x)+(180)-(0.30x)=330
(0.70-0.30)x=330-180
(0.40)x=150
x=(150)/(0.40)
x=375 mL
