Answer:

Subtract 225 from both sides. You have a 2 (or b 2 ) = 400 . Square root on both sides. Therefore, a 2 (or b 2 ), i.e. the other leg, is

20 cm.

Which statement is true about the extreme value of the given quadratic equation?

ICE Princess25 [194]

Answer:

Option B. The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

The correct quadratic equation is

$y=-3x^{2}+12x-33$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

Convert to vertex form

Factor -3

$y=-3(x^{2}-4x)-33$

Complete the square

$y=-3(x^{2}-4x+2^2)-33+12$

$y=-3(x^{2}-4x+4)-21$

Rewrite as perfect squares

$y=-3(x-2)^{2}-21$

The vertex is the point (2,-21)

therefore

The equation has a maximum value with a y-coordinate of -21

guapka [62]

Answer:

x = 14/9

Step-by-step explanation:

70 - 8x = 56 + x

- 8x - x = 56 - 70

- 9x = - 14

- x = - 14/9

What is the answer to this question having trouble answering it

Luda [366]

Answer:

Step-by-step explanation:

KL + KJ = 17

2 + 3x + 5x - 1 = 17 add like terms

8x + 1 = 17 subtract 1 from both sides

8x = 16 divide both sides by 8

x = 2

KL = 5x - 1 replace x with 2

5*2 - 1 = 9
