3 0

Answer:

$(3, -3)$

Step-by-step explanation:

{у = 3х - 12

{4х + 6у = −6

4x + 6[3x - 12] = −6

4x + 18x - 72 = −6

−6 = −72 + 22x

+72 + 72

___________

66 = 22x

__ ___

22 22

Find the area of an equilateral triangle with a side of 6 inches.

sweet-ann [11.9K]

Answer:

9 $\sqrt{3}$ in²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the length of a side )

Here s = 6, thus

A = $\frac{6^2\sqrt{3} }{4}$ = $\frac{36\sqrt{3} }{4}$ = 9 $\sqrt{3}$ in²

If A = (4,-5) and B = (7.-9), what is the length of AB?

Nookie1986 [14]

Answer:

Step-by-step explanation:

We can figure out the length of AB by using the distance formula.

$D = \sqrt{(7-4)^{2} + (-9-(-5))^{2} }\\ D = \sqrt{(3)^{2} + (-4)^{2} }\\D = \sqrt{9 + 16}\\D = \sqrt{25}\\D=5$

So the distance is 5
