Solve for x : x - 3(2 -x) = 4x - (x - 1) and explain please thanks
Hunter-Best [27]
Solving:
x - 3(2-x) = 4x - (x - 1)

Delete the first parentheses by the distributive property, with the distributive property, we multiply the '3' first, then resolve it and the second parentheses eliminate by changing the sign:
x - 6 + 3x = 4x - x + 1
<span>Now, put the numbers with letter (incognito) to the right and numbers without letter to the left, changing the signal when changing sides.
</span>x + 3x - 4x + x = 6 + 1
\diagup\!\!\!\!\!4x - \diagup\!\!\!\!\!4x + x = 7
\boxed{\boxed{x = 7}}\end{array}}\qquad\quad\checkmark

Answer:
\underline{The\:value\:of\:"x"\:is\:7}

zvonat [6]

Answer:

The answer is 792.

Step-by-step explanation:

I got the answer by first imagining how the 3d shape looks ike. Since one of the sqaure base length is 11 I found the base surface area by doing 11 times 11.My answer was 132. The since one of the slant length of the pyramid's triangle is 15, I did 11 times 15, my answer was 165. There are four triangles in the pyramid so I did 165 times 4, my answer was 660.

All the triangle surface area is 660 plus the sqaure surface are which is 132, that gave me my answer 792.
