Answer:
7
Step-by-step explanation:
Total number of surfaces of cube are 6.
Each surface is square.
And area of square is (side)^2
That means, total surface area will be 6 * (side)^2
From question,
294 = 6 * (side)^2 ( Surface area given)
=> 294 ÷ 6 = ( side) ^2
=> 49 = side^2
=> √49 = side
=> 7 = side
So, length of edge of cube is 7
Answer:
4) slope= 0
5) 
Step-by-step explanation:

4) Slope


= 0
The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).
5) Slope



Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.
