So you start off by seeing how many times 10 can go into 38, it would be 3 times and then your left with 8/10 and if you divide those by 2 you should get 4/5. so your final answer would be 3 4/5
Answer:
(x+1)(x+8)
Step-by-step explanation:
x^2+9x+8
You just need to multiply the first number to the last. (a·c) In this case *a* is jus a positive 1. Then, you just find a product to the result you got from (a·c) that when it is added together the result is the same as the one you have as ¨b¨.
Also the sign betwee b and c tells you that if it is positive both of your products are going to have the same sign, and if it is negative it means that they are going to be different,(one negative and one positive). If the sign is positive then go to the sign between a and b, this tells you what sign your factors will have.
<h2>x^2+9x+8</h2>
a·c=8
<u>Product Sum</u>
1,8 8
2,4 6
ect... ect...
x^2+x+8x+8
x(x+1) 8(x+1)
(x+1)(x+8)

The total is 219 miles.
He rides at 38 mph and walks at 4 mph for 8 hours. If he rides for h hours, he walks for 8-h hours.
Set them equal to each other:
219=38h+4(8-h)
Solve and you should get 5.5 hours on the bicycle and 2.5 hours walking.
''Decreased'' means subtract and ''times'' means multiplication so the algebraic expression should be 15 - 2 * p.
