Answer:
f = 27
Step-by-step explanation:
11 = f - 16
Add 16 to both sides.
11 + 16 = f - 16 + 16
27 = f
Answer:
Y=1.25x+3.50
Step-by-step explanation:
The problem is linear so it uses y=ax+b form. In this we can set the left group as x and the right group as y. Then use
(y2-y1) / (x2-x1) to find the slope. once the slope is found (1.25) we can find the y intercept by using one of our coordinates with our equation y-ax=b
12.25-1.25*7=b
b=3.5
now we put them all together to make
Y=1.25x+3.50
The square will have area
.. (9 cm)^2 = 81 cm^2.
The two triangles together will have area
.. (9 cm)*(12 cm) = 108 cm^2.
The sum of the areas of those three shapes is
.. 81 cm^2 +108 cm^2 = 189 cm^2
