Start by isolating the variable on one side by adding 43w^2 to both sides. The equation will read:

25w^2+5=0

*Subtract 5 from both sides*

25w^2=-5

*Divide both sides by 25*

w^2=-1/5

*Take the square root of both sides*

w=√(-1/5)

The square root of -1 is i. The square root of 5 remains √5

The answer is i/√5.

Answer:

See explanation

Step-by-step explanation:

Given triangle has its vertices at points A(-4,-2), B(1,3) and C(3,-2).

Find all sides lengths:

$AC=\sqrt{(-4-3)^2+(-2-(-2))^2}=\sqrt{(-7)^2+(0)^2}=\sqrt{49+0}=\sqrt{49}=7\ units\\ \\AB=\sqrt{(-4-1)^2+(-2-3)^2}=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}=5\sqrt{2}\ units\\ \\BC=\sqrt{(1-3)^2+(3-(-2))^2}=\sqrt{(-2)^2+(5)^2}=\sqrt{4+25}=\sqrt{29}\ units$

The longest side is AB.

By the Pythagorean theorem,

$AB^2=AC^2+BC^2\\ \\(5\sqrt{2})^2=7^2+\sqrt{29}^2\\ \\50=49+29\\ \\50=78$

This is false statemnt, so this triangle is not right triangle.

N f(x) = -3x+4, find f(-2)

hoa [83]

Answer: f(-2) = 10

Step-by-step explanation:

To fin f(-2), we must plug -2 in for x

y = -3x + 4

y = -3 (-2) + 4 = 6 + 4 = 10
