Answer:
A Multiply both length and width
B The area would be half
Step-by-step explanation:
Answer:
Just to recap, an equation has no solution when it results in an incorrect "equation".
For example:
Equation: x+3 = x+4
Subtract x: 3 = 4???
But clearly, 3 is not equal to 4, so this equation has NO SOLUTION.
Now onto our problem:
13y+2-2y = 10y+3-y
11y+2 = 9y+3
2y=1
y=1/2
9(3y+7)-2 = 3(-9y+9)
27y+61 = -27y+27
54y = -34
y = -34/54
32.1y+3.1+2.4y-8.2=34.5y-5.1
34.5-5.1=34.5y-5.1
5.1=5.1
infinite solutions
5(2.2y+3.4) = 5(y-2)+6y
11y+17 = 11y-10
17 = -10??
That's not true, so the option "5(2.2y+3.4) = 5(y-2)+6y" has no solution.
Let me know if this helps
28. 6x+42-20=6x
42-20=0
42-20 gives you 22
22=0
Statement is false
30. -2x-4=-2x-3-1
-2x-4=-2x-4
Statement is true because both sides are identical
32. 2x+8-5=2x+3
8-5=3
3=3
Statement is true for any value of x
34. 3x+(x+4)=18
3x+x+4=18
4x+4=18
4x=18-4
4x=14 (next divide both sides by 4)
x= 7 over 2
7/2
2040. 10 times 4 is 40. If it happens every ten years then when the Olympics happen 10 times it would be 2040.
