Answer:
A
Step-by-step explanation:
The easiest way to figure this out is to substitute in the variables. So for a, 2=-5+7 is correct, and 7=0+7 is correct as well. If you were to look at the other answers, you would see that the equation would not match up. Hope this helps!
Answer:
okay
Step-by-step explanation:
the probability of choosing blue marble is
p(blue)= 4/14
Answer: 1: 5(3x+4)
2: 6(x2+4x−3)
3: 5x(4x2−3x+2)
4: 4n2(4n2-3)
Step-by-step explanation:
A = lw
44 = 3 2/3 w
w = 44 / (3 2/3)
w = 12
164+219=383 is exact for estimate round 164 to 165 or 160 and 219 to 220 so
165+220=385 or 160+220=380
