Answer:
$486
Step-by-step explanation:
First you find the area of the window. The area of a square is equal to h×w, so we take 9×9 which equals 81. Since it costs $6 per square foot, we now take 81×6, which gives us an answer of $486.
C because you have to multiply the four measures together.
Answer:
30°
Step-by-step explanation:
Let the measure of the missing angle be x°
Therefore, by interior angle sum postulate of a triangle:
x + 60° + 90° = 180°
x + 150° = 180°
x = 180° - 150°
x = 30°
Thus the measure of the missing angle is 30°.
Answer:
y=-12x-9
Step-by-step explanation:
plug the value of m and b in the equation:
-y=12x+9
divide negative 1
y=-12x-9
A
The absolute value of -27 is 27, so it is the same number
