Answer: In Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.

Solve the system of linear equations below. <br><br> X+y=4<br> 2x+3y=0
deff fn [24]
X + y = 4...x = 4 - y

2x + 3y = 0
2(4-y) + 3y = 0
8 - 2y + 3y = 0
-2y + 3y = 0 - 8
y = -8

x + y = 4
x - 8 = 4
x = 4 + 8
x = 12

solution is : (12,-8)

What is a formula for the nth term of the given sequence? 20,23, 26...​
lord [1]

Answer:

17 + 3n

Step-by-step explanation:

20, 23,26 ..............

This is an arithmetic series

First term = a = 20

Common difference = second term -  first term

                               d = 23 - 20 = 3

nth terms = a + (n-1)*d

               = 20 + (n -1) *3

               = 20 + n*3 - 1*3

              = 20 + 3n - 3

               = 20 - 3 + 3n

              = 17 + 3n

I need help with this one pls!
Alex73 [517]

Hi there!

\large\boxed{b = \frac{a}{ac - 1}}

We can begin by making each fraction have a common denominator:

If we make each have a common denominator of ab, we get:

\frac{b}{ab} + \frac{a}{ab} = c

Simplify:

\frac{a + b}{ab}  = c

Multiply both sides by ab:

a + b = cab

Move b to the opposite side:

a = cab - b

Factor out b:

a = b(ac - 1)

Divide by (ac - 1):

\frac{a}{ac - 1} = b
