Question

can i get help with a math problem ?

Answer 1

maybe

Answer 2

a car travelling at 7.0m/s accelerates uniforly at 2.5m/s² to reach a speed of 12.0m/s. how long does it take for this acceleration to occur?

Answer 3

*uniformly

Answer 4

\[\chi2+5xy+4y2\]

Answer 5

those #2 are post to be the power can anyone help me ?

Answer 6

\[\Delta V=a \Delta t\]
therefore
\[12.5-7=2.5 \Delta t\]
therefore \[\Delta t= 2.2\]

Answer 7

ty

Answer 8

none of those answers are on my paper i think its done a different way

Answer 9

what is the question?

Answer 10

that math problem up top

Answer 11

what do you want to do with it? simplify?, complete the square ?, solve? ..etc?

Answer 12

welp it say to factor each trinomial

Answer 13

first look at the factors of each of the coefficients. In this case for x it is 1 and 1, and for y it is (4 and 1)or (2 and 2)
now you need determine what combination of factors corresponds to the middle term, to do this, look the sign of the middle and the last term, since they are both positive, you know that the factors must add to form the middle term.
looking at the factors, you can see that you need to att 4x1 +1x1 to equal 5, therefore the factorisation will be
\[(x+1y)(x+4y)\]
I hope this helps

Answer 14

thank you thats what i had got to. it gives you the answers on the bottom and i did not see that one. so it must be this answer (x + y) (x+ 4y) ;) *the invisible 1 ahh
