Answer:
Card 7
Step-by-step explanation:
2+5+7+8+9 =31
Multiples of 6: 6, 12, 18, 24, 30
31-9=22, No
31-8=23, No
31-5=26, No
31-2=29, No
31-7=24, Yes
The only way to get a multiple of 6 is to subtract card 7, so card 7 is the answer.
Answer:
x = 2√2
Step-by-step explanation:
This is a 45-45-90 triangle. This means that if the legs are x, then the hypotenuse is x√2.
In the case, the hypotenuse is already 4. So we have the equation:
x√2 = 4
Multiply both sides by √2
2x = 4√2
Divide both sides by 2
x = 2√2
