Answer:Z=1
Step-by-step explanation: if it is 11z+5, then... minus 9z on each side to get 2z+5=7. Minus 5 on each side to get 2z=2. Divide bboth sides by two to get 1z=1.
Answer:
(9x+10)(9x+10)
Step-by-step explanation:
Factor 81x^2+180x+100
81x^2+180x+100
=(9x+10)(9x+10)
Answer:
21 miles
Step-by-step explanation:
he runs 4.2 miles x 5 days
To solve this just use the distance formula, which is:
√(x2-x1)^2+(y2-y1)^2
1. plug into formula
√(1-5)^2+(3-3)^2
2. solve
√ (-4)^2+0^2= √16
3. Simplify
B. 4 units
