What are zeros of function y=2x2 -3x-20, and why

1 answer:

4 0

4 and -2.5

You can get this by first factoring the equation.

(2x + 5)(x - 4)

Then set both equal to zero and solve individually.

Find the perimeter of a triangle with vertices A(3, 1), B(2, -1), and C(-3, 2). Leave

natulia [17]

The perimeter of triangle is: 14.15 units

Step-by-step explanation:

First of all we have to find the lengths of sides of triangles

Given

A(3, 1), B(2, -1), and C(-3, 2)

The distance formula will be used to find the lengths of sides

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

So,

$AB = \sqrt{(2-3)^2+(-1-1)^2}\\=\sqrt{(-1)^2+(2)^2}\\=\sqrt{1+4}\\=\sqrt{5}\\=2.24\ unitsBC = \sqrt{(-3-2)^2+(2+1)^2}\\=\sqrt{(-5)^2+(3)^2}\\=\sqrt{25+9}\\=\sqrt{34}\\= 5.83\ units\\AC = \sqrt{(-3-3)^2+(2-1)^2}\\=\sqrt{(-6)^2+(1)^2}\\=\sqrt{36+1}\\=\sqrt{37}\\=6.08\ units$

The perimeter of triangle will be:

$P = AB+BC+AC\\= 2.24+5.83+6.08\\=14.15\ units$

Hence,

The perimeter of triangle is: 14.15 units

Answer:

m = 0

Step-by-step explanation:

distribute

7 + 35m + 2m = 7 +2m

add 35m + 2m

7 + 37m = 7 + 2m

subtract 2 from 37m

7 + 35m = 7

subtract 7 from 7

35m = 0

0 ÷ 35 = 0

so technically the answer is 0

I'm not 100% sure but I do believe this is right
