     17(k + 6) > 3(5k + 4)
17(k) + 17(6) > 3(5k) + 3(4)
    17k + 102 > 15k + 12
  - 17k           - 15k
      2k + 102 > 12
            - 102 - 102
                2k > -90

I'm not understanding this very well can anyone help me?

Answer:

x = 25

Step-by-step explanation:

Noting that these figures are similar, we set up and solve an equation of ratios:

x       30

---- = ------

15       18

Cross multiplying, we get:

18x = 30(15), or 3x = 5(15) = 75.  Then x must be 25.

Can u help me pls they are exponents with multiplication and division
Ronch [10]
When there is a multiplication involving exponents, we need to evaluate the numbers and each variables separately. In this case, we have 5 and 4 as the numbers, and w and h for the variables.

When we multiply 5 and 4 we get:
5 \times 4 = 20

For w, we have {w}^{6}, {w}^{4}, w. While we are multiplying the w's, we need to add the exponents together to get the final answer: {w}^{6} \times {w}^{4} \times w = {w}^{11}

For h's, there are {h}^{2}, {h}^{5}, {h}^{4}. When we apply the same thing to h's, we get {h}^{2} \times {h}^{5} \times {h}^{4} = {h}^{11}

For the final step, we need to write all of these together: 20 \times {w}^{11} \times {h}^{11} \: \: or \: \: 20 {w}^{11} {h}^{11} \: \: or \: \: 20 {(wh)}^{11}
