Answer:
80 centimeters taller
Step-by-step explanation:
First, convert Alex's height from meters to centimeters by multiplying by 100 because there are 100 centimeters in one meter to get 160 centimeters. Now multiply 160 centimeters by 1.5 to get Noah's height, 240 centimeters. Finally, since we need to find their difference in height, subtract Alex's height of 160 centimeters from Noah's height of 240 to get 80 centimeters.
8x +7y = 39 multiply everything by 2
2(8x +7y = 39)
16x +14y = 78
+4x - 14y= -68
-------------------------
20x = 10
20x /20 = 10/20
x = 1/2
Plug x into first formula
8 x + 7y =39
8(1/2) 7y=39
4+ 7y =39
4-4+7y =39-4
7y =35
7y/7 = 35/7
y = 5
(1/2, 5)
It increases at T because the behavior increased its speed
3x^3 – 5x^2 – 12x + 20
= (3x^3 – 5x^2) – (12x - 20)
= x^2(3x - 5) - 4(3x - 5)
= (3x - 5)(x^2 - 4)
= (3x - 5)(x + 2)(x - 2)
Factors: (3x - 5), (x + 2), and (x - 2)
Answer:
D.) 3x – 5
