Step-by-step explanation:
Reflex angle is more then 180 and less then 360
Answer:
27 units I think I am guessing it is
Step-by-step explanation:
(a-b)^2=(a^2-2*a*b+b^2)
4*(x^2-2x+1)-9=4x^2-8x+4-9=4x^2-8x-5
if you have to calculate the Δ
there is it: 4x^2-8x-5=0
Δ=b^2-4*a*c=64-4*4*(-5)=64+80=144
-b±Δ/2*a=8±12/8=
=8+12/8=20/8|:4=5/2
=8-12/8=-4/8|:4=-1/2
Answer:
C 24 ft wide, 18 ft deep
Step-by-step explanation:
there are 4 (2) in 8, so 4 x 6 = 24
there are 3(2) in 6, so 3 x 6 = 18
The larger scale drawing will be 24ft x 18 ft
