Answer:
9v
Step-by-step explanation:
You are just adding like numbers together. There is an imaginary 1 in front of the second v which makes it 9v
Answer:
a) (x/2 +3)^2
b) (5a -3b)^2
c) (x/3 +y/5)^2
d) (10b -3c)^2
e) (a/4 -2b)^2
Step-by-step explanation:
Assuming you can do that, write the terms of the quadratic in lexicographical order. (The square terms will be first and last.) Then the binomial is the "sum" of the square roots of the first and last terms with the sign of the middle term.
Using (e) as an example, the term are already in order. (In (d), they need to be rearranged.) The first term is 1/16a^2, and its square root is 1/4a = a/4. The last term is 4b^2 and its square root is 2b. The sign of the middle term is negative, so these two roots will be separated by a minus sign:
(a/4 - 2b)^2
The expression you want is the square of the binomial.
_____
As a check, you can make sure that double the product of these terms is the middle term of the trinomial you started with.
In this example, that double product is 2·a/4·(-2b) = -ab, which exactly matches the middle term you started with.
Answer:
x = 27/4
Step-by-step explanation:
3x + 2y = 12 and 5x – 2y = 42
Add the two equations together to eliminate y
3x + 2y = 12
5x – 2y = 42
-----------------------
8x = 54
Divide each side by 8
8x /8 = 54/8
x = 27/4
Answer:
33920 or 530 im not 100% sure
i think sorry if im wrong
Step-by-step explanation:
So 10/2 simplified is 5/1 which is on point 5. -9/2 is already simplified so in decimal form it is -4.5 which is -4 1/2, so you go down from 0 and mark it right where the BLUE dot is and the GREEN dot is 5/1. Hope this helps! :)
