Two artists are mixing up green paint for a mural. The first artist, Shane, mixes 3 parts blue and 2 parts yellow to make a shad
11Alexandr11 [23.1K]

Answer:

Shane's green paint mixture with be more yellowish because the sum of yellow paint is much closer to mixing than the Nora's paint. I don't really

Step-by-step explanation:

because the sum of yellow paint is much closer to mixing than the Nora's paint. I don't really know how to say it. Wait

If you really think about it when 3 parts blue and 2part yellow it means that there 1 more blue than yellow

But if you mix 5 parts blue and and 3 yellow it means that there are 2 more blue than yellow. As we know yellow is a lighter color so its harder to keep the color while mixing and having more blue means that the mixture will be less yellowish more blueish or how we say it. i dont really know how to explain it better but the answer is for sure right

Given: F(x) = 2x2+ 1, G(x) = 2x - 1, H(x) = x F(3) + G(4) - 2H(5) = 16 26 34
Roman55 [17]

Answer:

  16

Step-by-step explanation:

Put the numbers where the variables are and evaluate:

  F(3) = 2(3)^2 +1 = 19

  G(4) = 2(4) -1 = 7

  H(5) = 5

Then the desired sum is ...

  F(3) +G(4) -2H(5) = 19 +7 -2(5) = 16

The area of a gymnasium is (27x + 18) square units. Factor 27x + 18 to find possible dimensions of the gymnasium.
Veronika [31]

Answer:

Dimension of gymnasium= 9 units and (3x+2) units.

Step-by-step explanation:

We have been given the area of a gymnasium is 27x+18 square units. We are asked to find possible dimensions of gymnasium by factoring our given expression for area of gymnasium.

Let us factor our greatest common factor of our given expression. We can see that 9 is the GCF of our given expression.

(9\times 3x+9\times 2)

Upon factoring out 9 from our given expression we will get,

9(3x+2)

Therefore, the possible dimensions of the gymnasium will be 9 units and (3x+2) units as we will get the same area for gymnasium by multiplying these both dimensions.
