B. 24x2 is the correct answer
The brackets make the answer positive so you were just do 48÷6 which is 8and then 35÷7 which is five and you add 8+5 and you get 13
Answer:
Step-by-step explanation:
In a pen there are 200 animals,
25 of which are ducks,
Number of turkeys
50% are turkeys
= 50% × 200
= 100 turkeys
and
Numbers of chickens
75% are chickens.
= 75% × 200
= 150
How many animals are ducks, turkeys and chickens?
1 and 3/5 is bigger
because from both of the numbers u change 1 of them to fraction form or decimal form to make both of them the same form so i changed to decimal which i felt easy to compare with
Answer:
Step-by-step explanation:
hello :
5x²+8x-4 quadratic expression when : a = 5 and b=8 and c= -4
∆ = b²-4ac ∆ = 8²-4(5)(-4) = 64 +80 = 144 = 12²
X1 = ( -b -√∆)/2a X1 = (-8-12)/10 = -20/10= -2
X2 =(-b+√∆)/2a X2 = (-8+12)/10 = 4/10 = 2/5
us factorisation : a(X-X1)(X-X2)
5x²+8x-4= 5(x+2)(x-2/5) = (x+2)(5x-2)
you can verify ; (x+2)(5x-2) = 5x²-2x+10x-4 = 5x²+8x-4
