Given:
Two figures.
To find:
The area of the shaded regions for both figures.
Solution:
In first figure, the shaded area is a triangle with base 15 units and height 12 units. So, the area of the shaded region is equal to area of the triangle.
Therefore, the area of the shaded region is 90 square units.
In the seconds figure, we need to subtract the area of square from the area of triangle, to get the area of the shaded region.
Area of triangle with base 15 and height 18 is:
Area of the square with sides 6.
Now, the area of the shaded region is:
Therefore, the area of the shaded region is 99 square units.

Answer:
b^2+2*a*b+a^2
Step-by-step explanation:
Hi there!
To find f(1), plug in x=1 into the equation
f(1) = -4(1) + 7
= -4 + 7
= 3
That's your answer.
Have an awesome day! :)

Answer:
The value of x is 11.
Step-by-step explanation:
Consider the provided information.
It is given that 
We know that:
Now if we divide the number 81 with 32 it will gives us remainder 17.
This can be written as:
Now use the property: 
17²=289, if we divide 289 with 32 it will gives us remainder 1, thus.
Multiply both the sides by 3³.
Hence, the value of x is 11.
