hettie is stacking paper cups .each stack of 15 cups is 6 inches high. what is the total heightvof 10 stacks of cups ?
Maslowich
60 inches is the answer.

In this case the amount of cups do not matter only the height because that's what it's asking for.

If each stack is 6 inches we would have to multiply that by 10 because there are 10 stacks.

6 x 10 = 60 inches tall

How do I do this I’m not sure on this one
jonny [76]
Hi! So basically what you'll be doing is multiplying the exponents together :))
So It'd be 3x5 which is 15 so it'd be 10 to the power of 15.

Hope I helped :)) and ask more if you need help

How can we factorise the expression: 2x^6+17x^3+8?​
LekaFEV [45]

Answer:

(a + 2)( {a}^{2}  - 2a +  4 )(2 {x}^{ 3}  + 1)

Step-by-step explanation:

2x^6+17x^3+8 \\  = 2x^6+16x^3 +  {x}^{3} +8 \\  =  2{x}^{3} ( {x}^{3}  + 8) + 1( {x}^{3}  + 8) \\  = ( {x}^{3}  + 8)(2 {x}^{ 3}  + 1) \\  = ( {x}^{3}  +  {2}^{3} )(2 {x}^{ 3}  + 1)  \\  = (a + 2)( {a}^{2}  - 2a +  {2}^{2} )(2 {x}^{ 3}  + 1)   \\  = (a + 2)( {a}^{2}  - 2a +  4 )(2 {x}^{ 3}  + 1)  \\
