If you multiply the dark inside one and the outside one then add them up it will give you the answer!<span />
(a+b)(a-b)=a^2 - b^2
so
<span>(4x-7)(4x+7) = 16x^2 - 49
answer
</span>16x^2 - 49
The one on the right is correct. please give brainliest.
<span>Visualize that out of the 90 caps, how many were green? 18 were green. So how many were not green? 90 caps - 18 caps = 72 caps. That means 72 caps were not green in that sporting good order. Therefore, the probability of one cap selected at random from the total 90 caps will not be green will be 72/90 which is roughly 0.8
or
80 percent. </span>
0.4%, turn it into a decimal, which is 0.004
0.004*100= 0.4
