The area of the composite shape is 136 square cm
<h3>Area of a composite function</h3>
The area of the composite function is expressed as;
Area = area of triangle + area of rectangle
Area of the composite shape = (1/2* 4 * 5) + (7*18)
Area of the composite shape = 10 + 126
Area of the composite shape = 136 square cm
Hence the area of the composite shape is 136 square cm

The other side of 100° is 80 and 80 + 70 = 150
A triangle equals to 180 so..
180 - 150 = 30
The value of x is 30.
Y^2-9y+81 can not be factored with any rational numbers
We have that
x²<span>-6x+7=0
</span>Group terms that contain the same variable
(x²-6x)+7=0
Complete the square Remember to balance the equation
(x²-6x+9-9)+7=0
Rewrite as perfect squares
(x-3)²+7-9=0
(x-3)²-2=0
(x-3)²=2
(x-3)=(+/-)√2
x=(+/-)√2+3
the solutions are
x=√2+3
x=-√2+3
