The area should be 48 in squared
Answer:
a) area = side²
225 in² = side²
side = √225 = 15 inches
b) 15 inches per side x 4 sides x $1.35 per inch = $81.00
Step-by-step explanation:
Answer:
QR=18
Step-by-step explanation:
QR/QO =QS/QP (proportionality theorem...OP||RS )
QR/39 =24/52
52QR = 24(39)
52Q2=936
QR=18
Answer:
![(g\cdot f) = -3x^2-3](https://tex.z-dn.net/?f=%28g%5Ccdot%20f%29%20%3D%20%20-3x%5E2-3)
Step-by-step explanation:
![f(x) = x^2 + 1](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%20%2B%201)
![g(x) = -3](https://tex.z-dn.net/?f=g%28x%29%20%3D%20-3)
The problem state to multiply the function
and
so the symbol seems to be incorrect.
We actually want to calculate
![g(x) f(x) =gf(x) = (-3) \cdot (x^2+1)= -3x^2-3](https://tex.z-dn.net/?f=g%28x%29%20%20f%28x%29%20%3Dgf%28x%29%20%3D%20%20%28-3%29%20%20%5Ccdot%20%28x%5E2%2B1%29%3D%20-3x%5E2-3)
Note
![g\circ f(x)=g(f(x))=g(x^2+1)=-3](https://tex.z-dn.net/?f=g%5Ccirc%20f%28x%29%3Dg%28f%28x%29%29%3Dg%28x%5E2%2B1%29%3D-3)
