1 answer:
Mariana [72]3 years ago
5 0

Answer:

Example 11 answer = 12

Step-by-step explanation:

40, 36, 32, 28

is an arithmetic sequence.

The first term (a) is 40

The common difference (d) is -4

The formula for finding the nth term (X_{n} in an arithmetic sequence is;

X_{n} = a + d(n - 1)

X_{8} = 40 + -4(8 - 1)

X_{8} = 40 - 28 = 12

One leg of a right triangle is 28 inches longer than the other leg, and the hypotenuse is 52 inches. Find the lengths of the leg
katovenus [111]

Step-by-step explanation:

Let x represent the missing sides measurement.

x+x+28=52

combine like terms

2x + 28 = 52

subtract 28 from both sides

2x + 28 = 52

     - 28  - 28

2x = 24

divide both sides by 2

x = 12

plug it back in

one leg is 12 inches

the other leg is 40 inches
