Answer:

x equals 9.

The largest angle is 90.

Step-by-step explanation:

$10x + 3x + 7x = 180 \\ \frac{20x}{20} = \frac{180}{20} \\ x = 9$

$x = 9 \\ 10x \\ 10(9) \\ 90$

It is a) 6.5 because the formula is lwh/3 and the length and width are both 2 and the height is rt24 because 25-1 is 24 (Pythagorean Theorem) and so when you solve, you get about 6.53 and that rounds to 6.5

Determine the direction that this parabola opens y=x^2-6x

nalin [4]

Answer:

the graph of the parabola opens upwards.

Step-by-step explanation:

For any quadratic equation of the form

$ax ^ 2 + bx + c$ is true that:

if the main coefficient "a" is negative then the graph of the parabola opens downwards.

If the main coefficient "a" is positive, the parabola opens upwards

In this case the parabola is $y=x^2-6x$

Note that $a=1$ and $a>0$ therefore the graph of the parabola opens upwards.

Someone answer this Please

Ainat [17]

The given triangle is a Right angled triangle,

So, by applying Pythagoras theorem :

${c}^{2} = {12}^{2} + 9 {}^{2}$

=》

${c}^{2} = 144 + 81$

=》

${c}^{2} = 225$

=》

${c} = \sqrt{225}$

=》

$c = 15$

hence, value of c = 15 mi
