Answer: Rosie is incorrect because she needs to do the exponent before subtracting.
49 would be in the next space after 42 because this sequence is counting by 7s
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67

Step-by-step explanation:
100:
25x4=100
50x4=200g
75x4=300g
75x4=300g
100x4=400ml
40:
25x1.6=40
50x1.6=80g
75x1.6=120g
75x1.6=120g
100x1.6=160ml
