Answer:
equation~ 2x + 5= 2X + 8
Value of X~ 0.3
Perimeter:13
Step-by-step explanation:
equation: 2x + 5 =2x +8
2x + 5= 2x+ 8
4x + 5= 8
4X= 13
x= 0.3
value of X: 0.3
Perimeter: 13
(7+3)a^4
Hope this helps :D
Answer:
108 square feet
Step-by-step explanation:
First you want to break up the "L" into two parts. These parts can be seens as a and b. You need to find out the length on the left hand side, and half of it is 6ft as seen, so if half of it is 6ft, then you need to find the other half, which is obviously 6ft. 6+6=12, and to find the area of the thinner rectangle, multiply 2*24=48. That would be the area of section a. Section b is the bottom section and what you want to do is multiply 10*6 because this is how you would find the area of section b, which would be 60. 60+48=108. I know I was not very descriptive but I still hope this somewhat helps. I also might be wrong because of the fact that it says surface area despite the fact that this shape is 2D.
Both the vertical and horizontal cross-section would be a square. The cross-sections are the same because all of a cube's dimensions are the same. A cube is made up of 6 congruent square faces.
Answer: y = (-2/5)x - 7
This is the same as writing 
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7
