Answer:

-20

Step-by-step explanation:

2(xy-7)

When x=-1 y=3

Substitute the value of x and y in the equation given

Dealing with the bracket first

xy=-1×3

xy=-3

Substitute it into the bracket (-3-7)

=-10

Then back to the question

2(-10)

= -20

X=-1
y=3

2(xy-7) = ?

Substitute the numbers
2(-1x3-7)

Use BIDMAS
2(-3-7)
2(-10)
-20

Find x.______________a0

velikii [3]

Answer:

$x=4$

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

$\frac{2}{y}=\frac{y}{6}$

$y^2=12$

$y=\sqrt{12}$

$y=2\sqrt{3}$

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

$a^2+b^2=c^2$

$2^2+(2\sqrt{3})^2=c^2$

$4+12=c^2$

$c^2=16$

$c=4$

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

$x=4$
