Please answer!!

HACTEHA [7]

Answer:

See below

Step-by-step explanation:

$f(x)=3x^2+6x-24\\\\f(x)=3(x^2+2x-8)\\\\f(x)+3(9)=3(x^2+2x-8+9)\\\\f(x)+27=3(x^2+2x+1)\\\\f(x)=3(x+1)^2-27$

Here, we can see that the vertex of the parabola is $(-1,-27)$ when we compare to the equation $y=(x-h)^2+k$ with vertex $(h,k)$ .

A second point you could plot is the y-intercept, when $x=0$ :

$f(0)=3(0+1)^2-27\\\\f(0)=3-27\\\\f(0)=-24$

So, your y-intercept is $(0,-24)$ .

18. The area of a right triangle is 30 cm². The length

Olenka [21]

Answer:

Step-by-step explanation:

The area of a triangle is calculated with the following formula:

$\frac{1}{2} *b*h$ (b: base, h: height (or legs))

We can use this formula to find the length of the other leg:

30 = $\frac{1}{2} *b*h$ multiply both sides with 2 to get rid of fraction

60 = b*h one of the leg's length is given as 5 so

60 = 5*h divide both sides by 5

12 = h is the length of the missing leg.
