What is the area of this parallelogram? 10.35 cm² 12.5 cm² 20.25 cm² 30.6 cm² Parallelogram A B C D is composed of a square and
Taya2010 [7]

Answer:

30.6 cm²

Step-by-step explanation:

The area of the parallelogram is simply the sum of the areas of the component three shapes - the square and the two triangles.

Area of square = 4.5 cm × 4.5 cm = 20.25 cm²

Area of two triangles = 2 ×(1/2) × 2.3 cm × 4.5 cm = 10.35 cm²

Area of parallelogram =  20.25 cm² + 10.35 cm² = 30.6 cm²

Two solutions of the equation Ax+By = 1 are (2, -1) and (-3,-2). Find A and B.
kati45 [8]

Answer:

Substitute in the values of both given coordinates & form 2 equations:

\left \{ {{A(2)+B(-1)=1} \atop {A(-3)+B(-2)=1}} \right. \\\\=\left \{ {{2A-B=1} \atop {-3A-2B=1}} \right.

Find the value of B from the equation 2A - B = 1:

2A-B=1\\-B=1-2A\\B=2A-1

Substitute in the B-value to the other equation:

-3A-2B=1\\-3A-2(2A-1)=1\\-3A-4A+2=1\\-7A=1-2\\-7A=-1\\A=\frac{-1}{-7} =\frac{1}{7}

Find the B-value using the equation from before:

B=2A-1=2(\frac{1}{7})-1=\frac{2}{7} -\frac{7}{7} =-\frac{5}{7}  

Therefore the equation Ax + By = 1 would equal:

\frac{1}{7} x-\frac{5}{7} y=1
