9. Provided that we actually have a 2-dimensional triangle, the length of the hypotenuse is always greater than the length of either of the two legs.

Essay. Proving that two triangles are congruent establishes the fact that if one is placed directly over the other, the triangles appear to be and are exactly the same. Thus, corresponding parts of the triangles (such as the hypotenuses) are identical in length.

9.) The length of the hypotenuse is greater than the legs but is less then the legs combined.

Assign two variables for each problem, and write the equations. Do not solve.

Price of boots is represented as x, price of tennis shoes is represented as y. x-y=44.38 x+y=196.12 Isolate x. (Or y, if you wanted to) x=y+44.38 x=196.12-y Set them equal to each other. y+44.38=196.12-y Solve for y. Then plug it in to either of the two original equations to find x. x=120.24 y=75.86 Note: This is assuming that the boots are more expensive than the tennis shoes. If the tennis shoes are more expensive than the boots, then the prices would be switched. I didn't find this clear in your question.

Harold and Millicent are getting married and need to combine their already-full libraries. If Harold, who has 1/2 as many books

slavikrds [6]

Answer:

2/3

Step-by-step explanation:

Let x be the number of books that Millicent has. So the number of books that Harold has is x/2. And the number of book that Harold is bringing to the new home is (x/2)/3 = x/6.

The home has enough room for another half of Millicent's books, which is x/2. So the total books capacity of the new home is

$\frac{x}{6} + \frac{x}{2} = \frac{x}{6} + \frac{3x}{6} = \frac{4x}{6} = \frac{2x}{3}$

Since x is also the number of books in Millicent's old library capacity, we can conclude that the fraction of Millicent's old library capacity to the new home's library capacity is 2/3, or 2 thirds

Multiply 3x^2-2x and 2x^2+3x-1

Mnenie [13.5K]

Answer:

6 $x^{4}$ + 5x³ - 9x² + 2x

Step-by-step explanation:

Given

(3x² - 2x)(2x² + 3x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

= 3x²(2x² + 3x - 1) - 2x(2x² + 3x - 1) ← distribute both parenthesis

= 6 $x^{4}$ + 9x³ - 3x² - 4x³ - 6x² + 2x ← collect like terms

= 6 $x^{4}$ + 5x³ - 9x² + 2x
