Answer: 229.5m^2
Step-by-step explanation: 18x12.75=229.5, to find the A you need to multiply the HxW.
It’s in quadrant 1.
It goes like this:
2 1
3 4
Answer:
- x = 37
- DG = 22
- AG = 44
- AD = 66
Step-by-step explanation:
We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...
(x+7) = 2(x -15)
x + 7 = 2x - 30 . . . . eliminate parentheses
37 = x . . . . . . . . . . .add 30-x
Then AG = 37+7 = 44
and DG = 37-15 = 22.
Of course, AD = AG +GD = 44 +22 = 66
Answer:
d
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 6 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = - , then
y = - x + c ← is the partial equation
To find c substitute (5, - 7) into the partial equation
- 7 = - 2 + c ⇒ c = - 7 + 2 = - 5
y = - x - 5 ← equation of perpendicular line → d
