A brace for a shelf has the shape of a right triangle. its hypotenuse is 14 inches long and the two legs are equal in length. ho
maks197457 [2]
To answer this item, we make use of the equation derive from the Pythagorean theorem for right triangles which states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the two shorter sides. If we let x be the measure of both the shorter sides (we call this as legs), we have,
                         (14 in)² = (x²) + (x²)
Simplifying the equation,
                         196 in² = 2x²
Divide both sides of the equation by 2,
                         98 in² = x²
To get the value of x, we get the square root of both sides of the equation,
                         x = sqrt (98) = 7√2 inches

Hence, the measure of each leg of the right triangle is 7√2 inches or approximately 9.9 inches.

Find the quotient: (x2−5x+8)÷(x+2)
Aneli [31]

Answer:

Quotient = x - 7

Step-by-step explanation:

We are dividing x^2 - 5x +8 by x + 2

x + 2√x^2 - 5x + 8

Starting with dividing by x

x - 7

x + 2√ x^2 - 5x + 8

Multiplying x by x + 2

x

x + 2√ x^2 - 5x + 8

-

x^2 + 2x

= -7x + 8

Step ii, pick -7 for division

-7x + 8

-

-7x - 14

= +8 -(-14)

= 8+14

= 22

The answer is

( x - 7) remainder 22

(x - 7) is the quointent

22 is the remainder

9a-18b+21c apply distributive property to factor out gcf of all three terms
horsena [70]
The GCF of the three terms (9a, -18b and 21c) is 3

Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c

So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)

Answer: 3(3a - 6b + 7c)

If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.
