Answer:
Equation: (2x+5)4=(2x+8)3
X: 2
Perimeter: 36
Step-by-step explanation:
You would multiply 2x+5 and 4 because there are four sides to a square, so the perimeter of the square would be 8x+20. This would go same for the triangle, making the perimeter 6x+24.
So 8x+20=6x+24 is your new equation. Then, you do the opposite of the order of operations, and add or subtract first. It would be easiest to subtract 20 and 6x from both sides.
That leaves you with 2x=4. Dividing 2 by both sides means x=2
You can plug this in to prove if it is correct.
16+20=36
12+24=36
Lmk if you get it!
X2-1 I think that's the answer because there's 1 less, 1 take away the x and squared!! hard to explain but that's how I thought about it
<h3>The surface area of cube is 162.24 square inches</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>

Where,
"s" is the length of each side of cube
From given,
s = 5.2 inches
Therefore,

Thus the surface area of cube is 162.24 square inches
So, the multiples for 4 and 10 are...
4,8,12,16,20...
10,20,30,40,50...
So, basically LCM means least common multiple which just means that from the two numbers that you're given (4 & 10) there is one number that goes into both of them and is the smallest amount.
So for 4 and 10, the numbers that go into both of them are 20 and 40. out of both of these numbers 20 is the lowest, making it the LCM. Hopefully that helped, and if it didn't then I'm sorry. Good luck with the rest queen.
