The length of the base of an isosceles triangle is x. The length of a leg is 2x - 4. The perimeter of the triangle is 52. Find x. X=

x = 12

Step-by-step explanation:

Since the triangle is isosceles then the legs are congruent.

Sum the 3 sides and equate to 52, that is

2x - 4 + 2x - 4 + x = 52

5x - 8 = 52 ( add 8 to both sides )

5x = 60 ( divide both sides by 5 )

x = 12

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
