Joan did 21 is not a prime number good luck!!!
The value of B is 48m. squared
This is because the formula for a triangle is (length×hight÷2)
So in this case, multiply 16 and 6 to get 96. Then divide 96 by 2 to get 48m. squared
The answer is 20x^2 - 198
So the scale is 3/4 cm for every 6 meters
So if you have 8 cm, we want to find the dimension of the actual wall
convert cm to meters
0.75 cm = 0.0075 meters
8 cm = 0.08 meters
Cross Multiply
0.0075x = 0.48
x = 64 meters
The vertex form is y=a(x-h)²+k
the vertex is (h,k)
so
y=-1(x-2)²+3
compare to
y=a(x-h)²+k
2=h and 3=k
the vertex is (2,3)
4th option
