There are 120 choices.
5 × 4 × 3 × 2×1 = 120 choices
Answer:
54
Step-by-step explanation:
The two angles add to 90 degrees since they are complementary
the ratio is 3:2
Multiply by x
3x:2x
Add them together and set equal to 90
3x+2x=90
5x=90
Divide each side by 5
5x/5 = 90/5
x = 18
The first angle is 3*18 = 54
The second angle is 2*18 = 36
The correct option for this question would be C.
Answer:
(x+1)(x+2)
Step-by-step explanation:
x^2 + 3x + 2
find what multiples to 2 and adds to 3
Factors of 2 are 1 and 2, 2 + 1 = 3.
so the binomial would be (x+1)(x+2)
and then you would need to do FOIL to check
First: x * x = x^2
Outer: x * 2 = 2x
Inner: x * 1 = x
Last: 1 * 2 = 2
Then simplify: x^2 + 2x + x + 2
x^2 + 3x + 2
Answer:
2.5 Miles
Step-by-step explanation:
4 k = ? Mile
1.6 k = 1 mi
4/1.6 is 2.5
1x2.5 equals 2.5
so 4 km should be 2.5 mi
4 k = 2.5 Mile
(x2.5)1.6 k = (x2.5)1 mi
