both had differences in geometry
Answer:
x=924
Step-by-step explanation:
348 + 926 = x + 350
we have two 2-terms additions in both sides of the equation.
348 and 350 are two <em>similar</em> numbers then x and 926 should be really <em>close</em> numbers.
(due to commutative property of additions 348 + 926 = 350 + x)
<em>since 348 has two units less than 350, then 926 must have two units more than x, and <u>x=924</u></em>
(indirect proportionality)
The volume of the prism is 144 ft^3. If we use the letter V to represent volume, the formula for the volume of a rectangular prism is V=length*width*height. When you plug in the numbers, the equation is V=12*6*2. When you multiply these three numbers together, you get 144. Because you are finding the volume, your units are cubed, so your answer is 144 ft^3. I have attached an image of this problem written out (I’m sorry if the image is bad, I drew it on my phone).

About 6.6088 (rounded to the nearest thousandth)
Answer:
A
Step-by-step explanation:
The student must have thought that every single arrowhead is a line of symmetry, so since there are 10 arrowheads, there must be 10 lines of symmetry. This is incorrect because if you look closely at the diagram, each line has 2 arrowheads, so the student is overcounting by a factor of 2. They should have just counted the number of lines, not arrowheads. Therefore, there must be 10/2 = 5 lines of symmetry, not 10. Hope this helps!
