A triangle has side measures of 8, 13, 15. Are these the measures of a RIGHT Triangle?

Mathematics

Answer:

No.

Step-by-step explanation:

Since we know the side lengths of the triangle, we can figure out whether or not this is a Pythagorean triple.

Pythagorean theorem: a^2 + b^2 = c^2

a and b are both smaller than c.

So,

8^2 = 64.

13^2 = 169.

15^2 = 225.

64 + 169 = 233.

233 is not equal to 225.

Therefore, this is not a right triangle.

The larger of two numbers is 15 more than three times the smaller number. If the sum of the two numbers is 63, find the numbers
Amanda [17]

Answer:

The smaller number equals 12, the larger number equals 51.

Step-by-step explanation:

x + (3x + 15) = 63

Combine like terms.

4x + 15 = 63

Subtract 15 from both sides.

4x + (15 -15) = (63 - 15)

4x = 48

Divide both sides by 4.

4x/4 = 48/4

x = 12

Check answer.

12 + (3(12) + 15) = 63

12 + 36 + 15 = 63

63 = 63

If f(x)=3^x+10x and g(x)=2x-4 find (f-g) (x) (urgent)
notka56 [123]

Answer:

(f - g)(x) = 3^{x} + 8x + 4

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 3^{x} + 10x - (2x - 4) ← distribute parenthesis by - 1

= 3^{x} + 10x - 2x + 4 ← collect like terms

= 3^{x} + 8x + 4
