Answer:
1.58
Step-by-step explanation:
Okay. We're solving for t because we need to know how many seconds. From the problem, we know the height (10), but we don't know when that height happens.
We can factor by multiplying -16 by 61 first to get -976 and see what multiplies to get -976 AND adds to get -7 at the same time. But we can also use the quadratic formula because, let's be honest, factoring can be a lot of extra work.
Plug both the plus and the minus versions into your calculator and...
There's no such thing as negative time, so -2.02 is automatically disqualified, leaving 1.58 as the answer.

Answer:
easy :) answer is 12x-8y
Step-by-step explanation:
all you do is combine like terms
1. the 10x + 2x which is 12x
