Answer:
Step-by-step explanation:
A to C
y = b + mx
b = y-intercept
m = slope of line
Looking at the line, the line crosses the y-axis at the coordinates (0,0). This means that the y-intercept is 0.
The slope formula is m=(y2-y1)/(x2-x1). Using the points on the line (-1, -3) and (1,3) we find that the slope is, 3.
Looking back we can see that our variables now have value so we can plug them into our formula.
y = b + mx
b = 0
m = 3
Substitute
y = 0 + 3x
Answer:
<u>1</u><u> </u><u> </u><u> </u><u>x</u><u> </u><u> </u>( a + b ) × h
2
<u>1</u><u> </u>x ( 9× + 4 + 12× -2) x h
2
<u>1</u> x ( 13× + 10× ) × h 7x + 8= 15× a squared + b squared is equals to c squared
2 10 x + × = 15×
<u>1</u><u> </u>x ( 23x ) x h 100× + × = 225
2 x = 225 - 100
x = 125
x = 11.1803398875
x = 11.2
11.5 x h
11.5 x 11.2
= <u>128</u><u>.</u><u>8</u> height is 11.2
Step-by-step explanation:
Formula for trapezium half multiplied by the top and the bottom multipliedby height. As u constantly glance at the
question we dont know the height .adjacent plus opposite gives u hypotenuse .
The lengths are 40t because. if you add the w up and you get 40
