Answer:
Step-by-step explanation:
You can split this irregular shape into a square and a trapezoid.
<u>The formula for a square is:</u>
<u />
<u>The formula for a right trapezoid:</u>
<u />
<em><u>Area of square:</u></em>
<em><u /></em>
<em><u>Area of right trapezoid:</u></em>
<em><u /></em>
<u>Add up the individual areas to find the overall:</u>
4 + 3 = 7
Step 1
Given; The equations in the elimination method are written in the standard form as ____
Step 2
Simultaneous linear equations can be solved using the elimination method. First of all, make sure that the equations are written in the standard form either Ax+By=C or Ax+By+C=0. In this method, we multiply both the equations with a non-zero number to make the coefficients of any one variable equal.
Thus the answer is; The equations are written in standard form as seen below
=========================================================
One method is to plot the points P(3,6) and Q(7,3) on the same xy grid. Plot a third point R at (3,3). See the diagram below.
A right triangle forms in which we can find the legs PR = 3 and RQ = 4. The hypotenuse is found through the pythagorean theorem.
a^2+b^2=c^2
3^2+4^2 = c^2
9+16 = c^2
c^2 = 25
c = sqrt(25)
c = 5
This is the length of PQ
-----------------------------------
Or you can use the distance formula which is effectively using the pythagorean theorem just in a slightly different format (though it may not be obvious).
