Answer:
1512
Step-by-step explanation:
substitute the equation with the numbers given
3(2)(3)²=54
base length is 54
height= 54+2=56
area= ½x base x height
=½x54x56
=1512
Answer:
19
Step-by-step explanation:
The markings on the triangle means that this is an equilateral triangle (All sides are the same length)
So, we can set the two equations we have equal to each other
4x + 7 = 3x + 10
x + 7 = 10
x = 3
Plug it into either equation
3(3) + 10 = 19
Answer:?
Step-by-step explanation:
The second one! I took this recently :)
Answer:
(2, -8)
Step-by-step explanation:
The coordinates of M are the average of the coordinates of X and Y.
-3 = (x + -8) / 2
-1 = (y + 6) / 2
Solving:
x = 2
y = -8
