C. It's understood that's there's a one in front of the sq rt of 2
So 3 sq rt of 2- 1 sq rt of 2 gives you 2 sq rt of 2
Answer:
81000000
Step-by-step explanation:
bracket one
3^2 = 9
9^2 = 81
bracket two
10^3 = 1000
1000^2 = 1000000
81 × 1000000 = 81,000,000
im not very good at explaining but ive tried to break it into parts just to make it a bit simpler to understand :)
Doug have 30 quarters and 15 dimes.
Step-by-step explanation:
Given,
Number of coins = 45
Worth of coins = $9.00 = 9.00*100 = 900 cents
Each quarter = 25 cents
Each dime = 10 cents
Let,
x be the number of quarters
y be the number of dimes
According to given statement;
x+y=45 Eqn 1
25x+10y=900 Eqn 2
Multiplying Eqn 1 by 10
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 15
Putting x=30 in Eqn 1
Doug have 30 quarters and 15 dimes.

C, a Point. The other ones wouldn't be the best or right option
Considering the numeric values of the function on the table, we have that:
(p + q)(2) = 1.
<h3>How to find (p + q)(2)?</h3>
We have to look at the table, find p(2) and q(2), then add the values, that is:
(p + q)(2) = p(2) + q(2).
From the table, we have that:
- When x = 2, p(x) = 3, hence p(2) = 3.
- When x = 2, q(x) = -2, hence q(2) = -2.
Then, the numeric value is given as follows:
(p + q)(2) = p(2) + q(2) = 3 - 2 = 1.
