Since it ate 38 pounds so just minus 394 by 38 so you get the weight before it eats. the answer should be 356 pounds

The perimeter of the triangle is 13 inches. What is the length of the shortest side?
netineya [11]

Answer:

shortest side = 3 in

Step-by-step explanation:

Sum the 3 sides and equate to 13, that is

x - 5 + 6 + \frac{x}{2} = 13, that is

x + 1 + \frac{x}{2} = 13 ( subtract 1 from both sides )

x + \frac{x}{2} = 12 ( multiply through by 2 to clear the fraction )

2x + x = 24

3x = 24 ( divide both sides by 3 )

x = 8

Thus

x - 5 = 8 - 5 = 3 and \frac{x}{2} = \frac{8}{2} = 4 , then

The shortest side is x - 5 = 3 in

4. Solve the equation using the quadratic formula.
Vikentia [17]

Answer:

A. x = -2, x = 1.25

Step-by-step explanation:

<u>Use the </u><u>quadratic</u><u> formula</u>

x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}

Once in standard form, <u>identify</u> a, b, and c from the <u>original</u> equation and plug them into the <u>quadratic formula</u>.

4x² + 3x - 10 = 0

a = 4

b = 3

c = - 10

x = \frac{-3+\sqrt{3^{2}-4x4(-10) } }{2x4}

<u>Simplify</u>

<u>Evaluate the exponent</u>

x = \frac{-3+\sqrt{9-4x4(-10)} }{2x4}

<u>Multiply</u> the numbers

x = \frac{-3+\sqrt{9+160} }{2x4}

Add the <u>numbers</u>

x = \frac{-3+\sqrt{169} }{2x4}

Evaluate the <u>square root</u>

x = \frac{-3+13}{2x4}

<u>Multiply</u> the numbers

x = \frac{-3+13}{8}

<u>Separate</u><u> the equations</u>

To solve for the <u>unknown variable</u>, separate into two equations: one with a plus and the other with a minus.

x = \frac{-3+13}{8}

x = \frac{-3-13}{8}

<u>Solve</u>

Rearrange and isolate the <u>variable</u> to find each <u>solution</u>

x = - 2

x = 1.25
