Step-by-step explanation:
Find the product, sum and factors which are P=56, S=15 and F=8,7 respectively.
r²+15r+56=0
replacing with the factors in the equation
=> r²+8r+7r+56=0
r(r+8)+7(r+8)=0
(r+8)(r+7)=0
=> r= –8 and –7
Answer:
5
Step-by-step explanation:
The equation of a straight line is :
y=mx+c
where m is the gradient and c is the y-intercept
so if m equals 5 then the gradient is 5
Answer:
8<em>h</em>
Step-by-step explanation:

<em>h</em> hours
plug in <em>h </em>for how many hours
8 divided by 6 is 1.3
1.3 hours to run 6 miles
