Answer:
is it multiple choice?
Step-by-step explanation:
Answer:
4. Yes 5.No 6. No
Step-by-step explanation:
To be short,a linear equation has a coefficient of only 1 degree.
If the degree is over 1 it isn't a linear equation.
4 is the linear equation since it x value 7x has a degree of 1.
5 isn't becuase it's x value has a degree of 5
6 isn't becuase it degree is 4.
4. 20 minutes
Explanation- It's the only answer with "minutes" as an answer.
Answer:
Step-by-step explanation:
In the first triangle, using Pythagorean's theorem, x^2+3^2=5^2, x = 4
In the second triangle, using Pythagorean's theorem, x^2+7^2=24^2, x = 25
In the third triangle, using Pythagorean's theorem, 8^2+15^2=x^2, x = 17
In the fourth triangle, using Pythagorean's theorem, x^2+8^2=10^2, x = 6
In the fifth triangle, using Pythagorean's theorem, 5^2+12^2=x^2, x = 13
Quotient = 213.21 ÷ 15.8 ≈ 13.494
≈ 13.5 to the nearest tenth.
