Question 10 The hypotenuse of a right triangle is I m longer than the longer leg. The other leg is 7 m shorter than the longer l
bonufazy [111]

Answer:

5, 12, 13

Step-by-step explanation:

let x be the longer leg then x + 1 is the hypotenuse and x - 7 the shorter leg

Using Pythagoras' identity in the right triangle

x² + (x - 7)² = (x + 1)² ← expand using FOIL

x² + x² - 14x + 49 = x² + 2x + 1

2x² - 14x + 49 = x² + 2x + 1 ( subtract x² + 2x + 1 from both sides )

x² - 16x + 48 = 0 ← in standard form

(x - 4)(x - 12) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 12 = 0 ⇒ x = 12

x = 4 , then x - 7 = 4 - 7 = - 3 ← not possible

x = 12, then x - 7 = 12 - 7 = 5 and x + 1 = 12 + 1 = 13

The lengths of the 3 sides are

longer leg = 12 m , shorter leg = 5 m and hypotenuse = 13 m

Please help I’m lost it has to be 3 or 2 or more answers by the way and I will except answers from Expert, Ace, or Genius or any
deff fn [24]
The correct answer is only A, because you need the tenths place to be greater than the number on the left, and not just the hundredths place.

P.S. Even though I'm a beginner, I took Multi-Variable calculus in 12th grade.
P.P.S. STOP PUTTING ON RANDOM ANSWERS ON QUESTIONS JUST SO YOU CAN GET THE POINTS!!!!!!

Hey guys, I got positive 2 for this one but there is only -2. PLS help! Solve the equation -25p – 2 = 48 for p. A. -2 B. 1 C. 3
KengaRu [80]

Answer:

p=-2

Step-by-step explanation:

-25p-2=48

Take 2 to the other side which becomes positive

-25p=48+2

-25p=50

Divide both sides by the coefficient of x that is -25

-25p/-25=50/-25

p=-2

2 1/3 ÷y=1 2/5 ÷(−1.1)
Arada [10]

Answer:

1.2x - 10.8 - 2.3x - 9.2 = -1.1x - 20; Rewrite as follows. (x 2y)(xy 2) = (x 2 x)(y y 2) ... x + 2.3; - x / 5 = 2; (x - 4) / (- 6) = 3; (-3x + 1) / (x - 2) = -3; x / 5 + (x - 1) / 3 = 1/5 ... 2 x 2 - 8 = 0; x 2 = -5; 2x 2 + 5x - 7 = 0; (x - 2)(x + 3) = 0; (x + 7)(x - 1) = 9; x(x - 6) = -9 ... For what value of the constant k does the quadratic equation x 2 +2x = - 2k .
