Area = length x height divide 2
so = (6x6)/2 - (3x2)
= 12 cm square
Answer:
y = 2x+3
Step-by-step explanation:
You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.
To find the slope, compare the coordinates of the two points marked on the line, (0,3) and (-3,-3).
slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2
Slope-intercept equation for line of slope 2 and y-intercept 3:
y = 2x+3

Answer:
A = -9, B = 65
Step-by-step explanation:
Take the square root of both sides of the equation:
h + 9 = ±√65
Subtract 9 from both sides of the equation:
h = -9 ± √65
Comparing this to the form
h = A ± √B
we see that A = -9 and B = 65.
_____
A lot of math is about matching patterns of numbers and variables. Here, you're asked to match the expression -9±√65 to the pattern A±√B and identify the values for A and B that make these expressions identical.
It should not be difficult to see that the stuff on the left side of ± is the value of A. That stuff is -9.
The stuff under the radical is the value of B. That stuff is 65.
