Answer:
38.3 square inches
Step-by-step explanation:
The product of length and width gives the area of a rectangle:
area = (9.00 in)·(4.25 in) = 38.2500 in²
Each contributor has 3 significant digits, so your rounding rule requires the answer be rounded to 3 significant digits:
area ≈ 38.3 in²
7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
The answer to this problem is c<span>0<span>m<span>100</span></span></span>
Divide everything by the "X" thing AND MOVE IT TO OPPOSITE SIDE
Hi there
14000=-2000t+20000
Solve for t to find the age of the car
2000t=20000-14000
2000t=6000
T=6000/2000
T=3 years
Hope it helps
