Answer:
Step-by-step explanation:
triangle area = (length*width)/2
height(length): x
base(width): 8x
area = 45
8x^2=45
solve for x
Answer:
142.5 cm2
Step-by-step explanation:
The small markings create a new height, so that would be 9.5 cm.
Multiply:
9.5x15=142.5
Therefore, the area is 142.5 cm2
9 3/10- 1 7/10
8 13/10 - 1 7/10
7 6/10
7 3/5
KE=1/2mv^2
50000=(0.5)(1000)v^2
v^2=50000/500
v^2=100
v=10 ms^-1
f(x) = x2 + 2x + 1, g(x) = 11x − 19 x<span>2 </span>+ 2x + 1 = 11x - 19 x2 - 9x + 20 = 0 (x-4)(x-5) = 0 x = 4, 5
