Answer:Negative negative one and 2/3
Step-by-step explanation:First take a4+1/2 that equals three force then 3/4+ X equals -3/4 3/4+ X minus X equals -3/4 minus X 3/4 equals -1 and threeFirst take a4+1/2 that equals three force then 3/4+ X equals -3/4 3/4+ X minus X equals -3/4 minus X 3/4 equals -1 3/4 -1 and 3/4÷3/4 equals -2 aive first take a4+1/2 that equals 3/4 then 3/4+ X equals -3/4 3/4+ X minus X equals -3/4 minus X 3/4 equals -1 3/4 -1 and 3/4÷3/4 equals -2 1/3! I hope this helps!
2(x+11) is equivalent to 3x+10x+12
Check the picture below.
so the surface area of the pyramid will be the sum of the areas of the base and the four triangular faces.
![\stackrel{\textit{\Large Areas}}{\stackrel{\textit{4 triangular faces}}{4\left[ \cfrac{1}{2}(7.5)(16) \right]}~~ + ~~\stackrel{\textit{rectangular base}}{(7.5)(7.5)}}\implies 240~~ + ~~56.25\implies 296.25~ft^2](https://tex.z-dn.net/?f=%5Cstackrel%7B%5Ctextit%7B%5CLarge%20Areas%7D%7D%7B%5Cstackrel%7B%5Ctextit%7B4%20triangular%20faces%7D%7D%7B4%5Cleft%5B%20%5Ccfrac%7B1%7D%7B2%7D%287.5%29%2816%29%20%5Cright%5D%7D~~%20%2B%20~~%5Cstackrel%7B%5Ctextit%7Brectangular%20base%7D%7D%7B%287.5%29%287.5%29%7D%7D%5Cimplies%20240~~%20%2B%20~~56.25%5Cimplies%20296.25~ft%5E2)
HOW TO:
* use slope intercept form
1) find the slope
slope = rise/run (rise divided by the run)
slope = -4/2
slope = -2
2) find the y-intercept (just the point where the line intersects the y-axis)
y-intercept is (0,-4)
3) use slope-intercept form:
y = mx + b (m stands for the slope, b stands for the y-intercept)
y= -2x + (-4)
y= -2x - 4
So your equation is y= -2x-4
Actually those 4 angles are equal to 110 because those are vertical angles
