Answer:
Step-by-step explanation:
-3x - 5 = 16
add 5 to both sides of the equation
-3x = 21
divide both sides by -3
x = -7
---------------------
-4(y - 2) = 12
distribute the -4 to everything in the parentheses
-4y + 8 = 12
subtract 8 from both sides of the equation
-4y = 4
divide both sides of the equation by -4
y = -1
ANSWER
80 units²
EXPLANATION
One way to solve this is to find the area of the blue square and the subtract the areas of the red triangles:
The blue square is 12 units long by 12 units wide. Its area is:
Then, the area of the big triangle, which has a base 12 units long and a height of 10 units, is:
The smaller triangle has a base of 4 units and a heigth of 2 units. Its area is:
So the total area of the figure is:
Answer:
100 cm
Step-by-step explanation:
Using the Pythagore theorem :
Imagine that your window is a triangle, and that the distance you search is AC
So you have :
AC² = AB² + BC²
AC² = 28² + 96²
AC² = 784 + 9216
AC² = 10000
AC = √10000
AC = 100
