Solve for x x=750+125.75x

olga2289 [7]

X=750+125.75x
subtract to variable (x) on one side
x-125.75x=750+125.75x-125.75x
-124.75x=750
divide -124.75 to get variable (x) by itself
-124.75x/-124.75=750/-124.75
x=-3000/499
or
x=-6 6/499
or
x=-6.01202

Answer:

126 square units

Step-by-step explanation:

Area of section 1 is 8 square units which is triangle and,

Area of triangle is = $\frac{1}{2}\times b\times h$

b= 2 units and height =8 units

So,

Area of section 1 = $\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}$

Same Area is of section 2 which is also a triangle and has same base and height.

So,

Area of Section 2 = $\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}$

Now the Area of section 3 which is square with side of 10 units

So,

Area of section 3 = $a^{2} =10\times10=100\quad \text{square units}$

Total Area of Trapezoid = $8+8+100=126 \quad \text{square units}$
