Answer:
no
Step-by-step explanation:
4x -3 = 16
x=19/4
4(x-3) = 16: Distribute the number in the parenthesis with 4 and you get:
4x-12=16
x=7
4x-12=16 is not the same as 4x-3=16
Therefore they do not have the same solution.
Answer:
41x² - 27x + 27
Step-by-step explanation:
Perimeter of Rectangle:
= 2(20x²-12x+4) + 2(5x²-5x+15)
= 40x²-24x+8 + 10x²-10x+30
= 50x²-34x+38
Perimeter of Triangle:
= 6x²+6x+3x+3+3x²-2x+8
= 9x²+7x+11
Difference:
(50x²-9x²)+(-34x+7x)+(38-11)
= 41x² - 27x + 27
Mars is the correct answer
Answer: A. 5,000 meters
Step-by-step explanation:
Starting with the smallest unit which is option C. There are 10 millimeters in one centimetre. Option c in centimeters is:
= 30,000 / 10
= 3,000 meters.
Option c is smaller than B and so is incorrect.
A meter is 100 centimeters. Option b in meters is;
= 6,000 / 100
= 60 meters
This is less than option A so is incorrect.
A kilometer is 1,000 meters so option A in meters is:
= 5,000 / 1,000
= 5 kilometers
This is higher than option d so option A is correct.
