A right triangle has a hypotenuse of 8 feet. One leg has a length of 5 feet. How long is the other leg?
posledela

THEOREM:

<u>Pythagorean theorem</u>:– In a right angled triangle, the sum of squares of two legs is equal to the square of hypotenuse.

ANSWER:

Let the other leg be p, by pythagorean theorem

p² = h² - b²

p² = (8)² - (5)²

p² = 64 - 25

p² = 39

p = √39 ft.

So, <u>Correct choice</u> - [B] √39 ft.

what is the algebraic equation 3 times the sum of a number and 7 is 2 less than five times the number
stealth61 [152]
Let n = number

"3 times the sum of a number and 7" translates to 3(n + 7)

"2 less than five times the number" translates to 5n - 2

The word "is" becomes the equals sign.

3(n + 7) = 5n - 2

I think you already asked this one.

20 POINTS PLEASE HELP ME!!!
Minchanka [31]

Answer:

p = -1

x=10

m < 7

Step-by-step explanation:

4(3p + 6 ) = 12

Distribute the 4

12p +24 = 12

Subtract 24 from each side

12p+24-24 = 12-24

12p = -12

Divide by 12

12p/12 = -12/12

p = -1


-5(x -4) = -30

Distribute the -5

-5x+20 = -30

Subtract 20 from each side

-5x+20-20 = -30-20

-5x=-50

Divide by -5

-5x/-5 = -50/-5

x=10



-3m + 15 > -6

Subtract 15 from each side

-3m + 15-15 > -6-15

-3m >-21

Divide by -3   remember to flip the inequality

-3m/-3 < -21/-3

m < 7
