Answer:

Step-by-step explanation:
Area of a triangle is given a half the product of base by the perpendicular height:

Given h=9cm, and b=2.9cm, the area is calculated as:

Hence, area of the triangle is 13.05 sq cm
Answer: 14
Step-by-step explanation: To find the mean you have to add the two numbers and divide by the amount of numbers (which is 2). 14 plus 2 is equal to 16. and 16 divided by two is equal to eight
The window is 2/3 yd by 1 yd, so its area is
.. area = length*width = (2/3 yd)*(1 yd) = 2/3 yd^2
Double that amount of material would be 4/3 yd^2 = 1 1/3 yd^2.
Y-5=-2(x-3)
The formula is y-y1=m(x-x1)
1. Find the slope
2. Replace y1 & x1 with the first point
Answer: y = 12 - 3x
Step-by-step explanation:
Move "x" to the other side.
y = 12 - 3x
