The length of a side of a triangle is 36. A line parallel to that side divides the triangle into two parts of equal area. Find t

pantera1 [17]

Answer:

18√2

Step-by-step explanation:

The area of the smaller triangle is 1/2 that of the larger one. Since the triangles are similar, the dimensions of the smaller triangle are √(1/2) those of the larger one.

36 · √(1/2) = 36 · (√2)/2 = 18√2 . . . . length of line dividing the triangle

Order of Operations: BPEMDAS

Algebra I

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-1, 4)

y-intercept (0, 2)

Step 2: Find slope m

Substitute: $m=\frac{2-4}{0+1}$
Subtract/Add: $m=\frac{-2}{1}$
Divide: $m=-2$

Step 3: Write linear equation

y = -2x + 2

Factor the equation 45x - 81

alex41 [277]

Answer:

Step-by-step explanation:

45x = 9*5*x

81 = 9*9

GCF = 9

Take 9 out using distributive property { a*b - c*b = b*(a-b)}

45x - 81 = 9*5x - 9*9

= 9*(5x - 9)

=9(5x-9)
