A triangle has side lengths of (7x-4)(7x−4) centimeters, (x+3)(x+3) centimeters, and (3y+2)(3y+2) centimeters. Which expression

Papessa [141]

Answer:

<u>This assumes that the question was meant to read:</u>

"A triangle has side lengths of (7x−4) centimeters, (x+3) centimeters, and (<u>3x+2</u>) centimeters." <u>And not </u>"A triangle has side lengths of (7x-4)(7x−4) centimeters, (x+3)(x+3) centimeters, and (3y+2)(3y+2) centimeters."

If the revision is correct, the perimeter is 11x + 1 cm

=============================================

<u>If the question was correctly written, then answer is:</u>

50x^2 - 50x + 9y^2 + 12 y + 29

===============

Step-by-step explanation:

(7x-4) cm

+ (x+3) cm

<u>+ (3x+2) cm</u>

11x + 1 cm

If the question was correctly written as is, then:

(7x-4)(7x−4) = 49x^2 - 56x + 16

+(x+3)(x+3) = + x^2 + 6x + 9

+(3y+2)(3y+2) = <u> +9y^2 + 12 y + 4</u>

50x^2 - 50x + 9y^2 + 12 y + 29 cm

In the graph below, the area above f(x) is shaded and labeled A, the area below g(x) is shaded and labeled B, and the area where

drek231 [11]

Answer: OPTION C.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

Notice that the line of f(x) is dashed. This means that the symbol of the inequality must be or $>$ .

Since the shaded region A is above the line, the symbol is $>$

Observe that its y-intercept is:

$b=3$

The line of g(x) is solid. This means that the symbol of the inequality must be $\leq$ or $\geq$ .

Since the shaded region B is below the line, the symbol is $\leq$ .

Observe that its y-intercept is:

$b=-2$ .

Based on this, we can conclude that the graph represents the following System of Inequalities:

$\left \{ {{y\leq 2x -2} \atop {y >-x + 3}} \right.$
