Answer:
1+2x=13
Step-by-step explanation:
the sum of= +
one=1
products of a number and 2= 2x
equals= =
thriteen=13
Put them all together:
1+2x=13
I think you are supposed to make the fraction equivalent so you know that 27/9 is 3, so you would do the same thing whatever number is supossed to be under 17 needs to equal to 2 when divided by 9. So you should probably know that 3 * 9 is 18 so x needs to be a number that when subtracted by 5 gives you 18. So x=23. Hope this is right and it helps!
<span>x−38.45=17.71 is your answer

B, 4x(2x2 + 3x)
divide both sides by 4 and you will get 2x2 + 3x to be the most factored form
Answer:
cos A = 6/10
Step-by-step explanation:
That'd be cos A. The cosine function is defined as the ratio
adjacent side
------------------------
hypotenuse
and here that ratio is cos A = 6/10.
