Answer:

Step-by-step explanation:

m<1 = m<2

8y - 6 = 7y

8y - 7y = 6

y = 6°

m<2 = 7y = 7(6) = 42°

Can someone help me with this problem

Answer:

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

A(-3, 0) , B(3, 2)

$AB=\sqrt{(3-(-3))^2+(2-0)^2}=\sqrt{6^2+2^2}=\sqrt{36+4}=\sqrt{40}=\sqrt{4\cdot10}=\sqrt4\cdot\sqrt{10}=2\sqrt{10}$

A(-3, 0), D(-2, -3)

$AD=\sqrt{(-2-(-3))^2+(-3-0)^2}=\sqrt{1^2+(-3)^2}=\sqrt{1+9}=\sqrt{10}$

AB = CD and AD = BC

The area of a rectangle:

$A=(AB)(AD)$

Substitute:

$A=(2\sqrt{10})(\sqrt{10})=(2)(10)=20$

The perimeter of a rectangle:

$P=2(AB+AD)$

Substitute:

$P=2(2\sqrt{10}+\sqrt{10})=2(3\sqrt{10})=6\sqrt{10}$

What is the value of discriminant in the equation shown below? x2+3x-6=0

Aloiza [94]

ANSWER

The discriminant is -3

EXPLANATION

The given quadratic equation is:

${x}^{2} + 3x - 6 = 0$

Comparing this equation to:

$a {x}^{2} + bx + c = 0$

we have

a=1, b=3, and c=-6

The discriminant is calculated using the formula,

$D = {b}^{2} - 4ac$

We substitute the values to get:

$D = {3}^{2} - 4(1)(3)$

$D = 9 - 12$

$D = - 3$
