An expression means that you may not be able to find a final value, and that it is acceptable to have x in the answer.

The formula for the area of a triangle is A=1/2*b*h

A=1/2*(5x^2+4x)*(2x^2) (distribute the 1/2)
A=(5/2x^2+2x)(2x^2) (distribute the 2x^2)
A=5x^4+4x^3

Hope this helps

write the equation of a line in any form that is parallel 2y = 4x + 8 through the point of (1,3) plz and thank you
V125BC [204]

Answer:

y = 2x+1

Step-by-step explanation:

2y =4x+8\\\\ Write \:in \: y =mx+b \:form\\\\\frac{2y}{2} = \frac{4x}{2} +\frac{8}{2} \\\\y =2x +4\\m =2\\(1,3) =(x_1,y_1)\\Substitute\:values\:into\:point-slope\:form\\\\y-y_1=m(x-x_1)\\y-3=2(x-1)\\y-3 = 2x-2\\y=2x-2+3\\y =2x+1

Plzzz help super easy and I'm running out of time!!!
11Alexandr11 [23.1K]

Answer:

y = 2x -5

Step-by-step explanation:

Given points: (0,-5)  (1,-3)

(x1, y1) = (0,-5)

(x2, y2) = (1,-3)

Calculate the slope:

m = (y2 - y1)/(x2 - x1)

m = [-3 - (-5)] / [1 - 0]

m = (-3 + 5) / 1

m = 2/1 = 2

Next, the y-intercept is the value of y when x = 0. One of your given points is the y-intercept, (0, -5). The y-coordinate is the value of b.

Therefore, the linear equation is: y = 2x -5

Answer:

Number of ways = 6

Step-by-step explanation:

Given:

Total number of choices = 4

Taken object choices = 2

Find:

Number of ways

Computation:

Number of ways =  [4 × 3] / 2!

Number of ways = [4 × 3] / [2 × 1]

Number of ways = [12] / [2]

Number of ways = 6
