Solve for a by simplifying both sides of the equation, then isolating the variable.
a = 1
You can’t solve this unless you have a number to plug in for y
Hi Nova
(4u³+6u²+7)+(6u³-2u+7)
= 4u³+6u²+7+6u³-2u+7
Combine like terms
( 4u³+6u³)+(6u²)+(-2u)+(7+7)
= 10u³+6u² -2u+14
There no like terms so you can not simplify the sum
I hope that's help and if you have questions please ask !
Answer:
120
Step-by-step explanation:
nCk or C(n, k) are ways to write the "combinations" function. That function tells you how many combinations of n things there are when they are taken k at a time.
Here, you have 10 vegetables, and you want to count the number of ways you can take 3 at a time. You are being asked to find the value of 10C3, or C(10,3). You do this by putting 10 where n is in the formula, and 3 where k is. Then do the arithmetic.
10C3 = (10!)/(3!(10-3)!) = 10·9·8/(3·2·1) = 5·3·8 = 120
120 3-vegetable plates may be made.
