Answer:
45.333...
Step-by-step explanation:
Try using a long division problem then try the area model strategy
instead of P+2x = y it should be P-2x=y
so then it is P-2x/2 =y
Answer:
First model gets the equation: y = 2 . 2^z
Second model gets the equation: y = 4^z
Third model gets the equation: y: = 4 . 2^z
Answer:
H 16x2–11x
Step-by-step explanation:
4(x2 – 3x) + 12x2 + x
4x^2-12x + 12x^2+x=
16x^2-11x
H 16x2–11x
