Square root of 11 because:
sqrt2^2 = 2
3^2 = 9
so C^2 or the hypotenuse would be the square root of 11
Answer:
5x + 10y = 125
Step-by-step explanation:
Let :
Number of nickel = x
Number of dime = y
Nickel = 5 cent
Dime = 10 cent
Total value = $1.25
Total value should be converted to cent since both dime and nickel are both in cent
= $1.25 * 100 = 125 cents
Therefore,
5x + 10y = 125 cents
2x+4x-4=80
6x-4=80
6x=84
84/6=14
Angle c = 4 x 14= 56 - 4 = 52
Hope this helps.
Answer:
never
Step-by-step explanation:
p->q means if p is true, then q must also be true
but since q is false, p->q is never true
Answer:
D. 13
Step-by-step explanation:
You can do the product in the straight-forward way ...
... (3 -2i)(3 +2i) = 3·3 +3·2i -3i·3 -(2i)(2i)
... = 9 +6i -6i -4i² . . . . . note the middle two terms cancel
Recognize that i = √-1, so i² = -1. Then the sum is
... = 9 -4(-1) = 9+4 = 13
