Answer:
6.2 ft
Step-by-step explanation:
You can find the area of the entire shape by finding the area of one of the split shapes individually
Formula for Square Area:
Length*Width
6*6=36
The area of the square is 36 in squared
Formula for Right Triangle Area:
Leg A*Leg B/2 (The lines which form the Right Angle)
6*6/2
36/2=18
The area of the right triangle is 18 in squared
Formula for the Equilateral Triangle Area:
Base * Height/2
6*6/2
36/2=18
The area of the equilateral triangle is 18 in squared
Now add all the sums up
36+18+18
=72
The total area of the shape is 72 in squared
Hope this helps!

Answer:
b-3x+19
Step-by-step explanation:
you have to open the bracket so 3*x=3x
3*3=9
therefore;3x+9+10=3x+19
Answer:
(-4;2)
Step-by-step explanation:
1. if y=1/2 x+4, then 2y=x+8; it is possible to re-write as x-2y+8=0;
2. if x+4y=4, it is possible to re-write it as x+4y-4=0;
3. if x-2y+8=0 and x+4y-4=0, then x-2y+8=x+4y-4; ⇒ -2y+8=4y-4; ⇒ 6y=12; ⇔ y=2.
4. if y=2, then it is possible to substitute its value into any equation given in the condition:
x+4y=4 (substitution y=2); ⇒ x+8=4; ⇒ x= -4.
5. finally x= -4; y=2. It means (-4;2)
PS. the suggested solution is not the only way to resolve this task.
