X = -33 + 42
x = 42 - 33
x = 9
Answer:
Bob will need 
of sod
Step-by-step explanation:
step 1
Find the area of the backyard
step 2
Find the area of the flower garden
step 3
Find the difference
Interest rate is 5% annually. After 4 years relative value of interest will be 1.05^4
Now we multiply that with starting funds and get
4000* 1.05^4 = 4862.03
La forma estándar de una ecuación de un círculo es% 28x-h% 29% 5E2 +% 2B +% 28y-k% 29% 5E2 + = + r% 5E2
donde Pt (h, k) es el centro y r es el radio
x ^ 2 + y ^ 2-10x + 4y + 4 = 0
completando los cuadrados para ponerlos en la forma estándar
x ^ 2 -10x + y ^ 2 + 4y + 4 = 0
(x-5) ^ 2-25 + (y +2) ^ 2-4 + 4 = 0
(x-5) ^ 2 + (y + 2) ^ 2 = 25
El centro es (5, -2) radio = 5
