The interior angles of a polygon add to 180°
3x - 11 + x - 8 + 2x + 7 + x + x + 8 = 180
8x - 4 = 180
8x = 184
x = 23

I presume you mean
x^(56) times x^(13) = x ^(56+13) = x^(69)
Answer:
3.375
Step-by-step explanation:
Volume = L x W x H
Volume = 1.5 x 1.5 x 1.5
Volume = 3.375
(2) + (2)
=> 8x - 6y = -46 ———(3)
(1) + (3)
=> 5x + 6y + (8x - 6y) = 20 - 46
=> 13x + (6-6)y = -26
=> 13x + 0y = -26
=> 13x = -26
=> x = -26/13
=> x = -2
=> 5(-2) + 6y = 20
=> 6y = 20 + 10
=> 6y = 30
=> y = 5
x = -2, y = 5 => C
Answer:
Step-by-step explanation:
The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.
