UW and VW are the same so 9
22.5-4.5= 18 then divide the 18 by 2 so 9
1a) 8 / (1/2) = 16 * 3 = 48
1b) 3sqrt(49) = 3 * 7 = 21
1c) (5+2)(-8) / (-2)^3 -3
(7*-8) / (-8 -3)
-56/-11
56/11
Answer:
<em>i: </em>x=-2, x=1
<em>ii: </em>x=-1/2
Step-by-step explanation:
Quadratic form:
You solve <em>i </em>by using FOIL (First, Outside, Inside, Last) because it is a multiplication problem.
<em>"first"</em> would be , which would equal
<em>"outside"</em> would be , which would equal
<em>"inside"</em> would be , which would equal
<em>"last" </em>would be , which would equal
Now you need to combine the terms so that they are one after the other
Combine like terms, and you should get:
i Solution
<em>You need to get the variable by itself.</em>
<em>Subtract two from both sides</em>
<em>Add one to both sides.</em>
ii Solution
<em>Add all the terms.</em>
$0.00995 is the correct answer.
$3.98/400=0.00995
C , the little 5 at the top represents how many times 7 is multiplied.
