3x^2 + 5xy + y, for X = 4 and Y = 2
= 3(4)^2 + 5(4)(2) + 2
= 3 * 16 + 40 + 2
= 48 + 40 + 2
= 90

What is the value of x given that figure ADCB
aleksley [76]

Answer:

Step-by-step explanation:

Because the trapezoid is isosceles, the two diagonals are congruent. This can be shown by ASA.

ACD = BDC          Properties of parallel lines.

DC = DC               A line is equal to itself

DBA = CAB           Property of parallel lines.

AC = DB                Parts of Congruent triangles are congruent

3x + 15 = 7x - 9     Add 9 to both sides

3x + 15 + 9 = 7x

3x + 24 = 7x          Subtract 3x from both sides.

24 = 7x - 3x

24 = 4x                  Divide by 4

24/4 = 4x/4

x = 6
