Answer:
784
Step-by-step explanation:
you take the 49 and times is by 16
there are 4 sides
This is the concept of algebra, to factor the expression we proceed as follows;
ab+4+a+4b
this can be written as:
ab+a+4+4b
factoring this we get:
a(b+1)+4(1+b)
=(a+4)(b+1)
the answer is (a+4)(b+1)
Answer:
It takes them 7minutes to finish 50env
Step-by-step explanation:
We know that jerry can stuff 7 in 2min and tom can do 4 per min, so 8 for every 2min.
So 8+7=15env for every 2min 7.5/min
15+15=30+15=45
50=15x/2 50*2=15x 100=15x 100/15=x x=6.67 then rounded it to 7min
Answer:
<em>x = 10.5</em>
Step-by-step explanation:
Answer:
Position of the particle is 20.
Step-by-step explanation:
Position function is integration of velocity function.
Velocity function is integration of acceleration function.
So, let's integrate the given a(t) to get v(t)
If we integrate v(t) then we get s(t)
It is given the values of s(0) =0 and s(1)=20
So, position of the particle is difference of 20, 0. That's 20-0 =20.
