PQ = 40 inches
The answer is C
Let X = the number of pennies.
The number of nickels would be 2X
A penny is 0.01 and a nickel is 0.05
Now you have:
0.01x + 2(0.05x) = 8.80
Simplify:
0.01x + 0.10x = 8.80
Combine like terms:
0.11x = 8.80
Divide both sides by 0.11:
x = 8.80 / 0.11
x = 80
Pennies = X = 80 total pennies.
Nickels = 2x = 2 *80 = 160 nickels.
-x + 6x - 1 - (3x - 4x - 1)
-x + 6x - 1 - 3x + 4x + 1
5x - 3x + 4x - 1 + 1
6x
(f-g)(x) = 6x
Answer:
The answer is 30
Step-by-step explanation:
To get a.b
For a = <wa, za> and b = <wb, zb>, the dot product represents multiplication sign.
We say,
a•b = (wa)(wb) + (za)(zb)
The next step is to substitute the given information into the above equation we generated.
Then we say,
a•b = 5•4 + 2•5
a.b = 20 + 10
a•b = 30
The answer is 30
Answer:
26 + 22i
Step-by-step explanation:
Given
(2 + 4i)(7 - 3i) ← expand product using FOIL
= 14 - 6i + 28i - 12i² ← i² = - 1
= 14 + 22i + 12
= 26 + 22i ← in standard form
