1 - True. If a number is divisible by 12 it's divisible by 6 and thus by 3
2 - False. A rhombus needn't have square angles
3 - False. the second proposition is unrelated to the first one, and doesn't allow us to deduce that cats have fur.
4 - False - We cannot link the first and second proposition in any way to make the third
Answer:
1500 grams.
Step-by-step explanation:
1.5 kg = 1500 grams
Original prism is 94 cm.
With the dimensions doubled is 376 cm.
As given Zahra has paper rectangles of different sizes.
Also, Every rectangle is 5 cm is longer than it's breadth.
So, if Length=L, then Breadth= L- 5
Or , if Breadth= B, then Length= B+5
or, if length is x and breadth is y ,then writing in terms of equation
→x=y+5
As you can see,there is not any proportional relationship between length and widths of these rectangles.
For the first one,
you multiply 5x and -5 to get -25.
Then you move the constant to the right and change the sign to get 3x= -21 +25.
Calculate the sum of -21+25 to get 4.
Divide both sides of the equation by 3 to get x=4/3.
So then your final answer is x=4
——
3
For the second one,
Distribute 7 through the parentheses to get 14x + 14+8=120
The you add 14+8 to get 22. Your equation should be 14x+22=120
Move the constant to the right side and change its sign to get 14x=120-22
Subtract 120-22 to get 98. Now your equation should be 14x=98
Divide both sides of the equation by 14 to get x=7.
Your finial answer for the second one should be x=7.

I hope this made sense.
