A+B+C+D+E=540°
4X+5+7X+6X+10+5X-5+4X+10=540
26X = 520
X = 520 : 26 = 20°
E = 4X + 10 = 80 + 10 = 90 °
Answer:
$197,4
Step-by-step explanation:
4 x 35 = 140 These are the four chairs before the sale.
35 x 18 / 100 = 6,3 35 - 6,3 = 28,7 Price of the chairs after the sale.
2 x 28,7 = 57,4
140 + 57,4 = 197,4
0.5kg because 1kg is equal to 1000g
Wih roots r1 and r2
the factors are (x-r1)(x-r2)
roots 4 and -8
(x-4)(x-(-8))
(x-4)(x+8)
x^2+4x-32 is the equation
either (x-4)(x+8) or x^2+4x-32
At z= 12:
z/4 -8z+ 2(z-5)
= 12/4 -8*12+ 2(12-5)
= 3 -96+ 2*(7)
= -93+ 14
= -79
The correct answer is A. -79~
