Answer:
£40
Step-by-step explanation:
3+5=8
160÷8= 20
20× 5=100
20×3=60
100-60=40
-3a^2 - b^3 + 3c^2 - 2b^3......when a = 2, b = -1, and c = 3
-3(2^2) - (-1^3) + 3(3^2) - 2(-1^3) =
-3(4) -(-1) + 3(9) -2(-1) =
-12 + 1 + 27 + 2 =
-12 + 30 =
18 <==
Answer: All real numbers are solutions
Step-by-step explanation:
first lets distributive the 2(4x+1) to get 8x+2 because 2*4x= 8x and 2*1= 2
now the equation is 8x+2-5x+2= 3x+4
(COMBINE LIKE TERMS)
8x-5x=3x
2+2= 4
now the equation is 3x+4= 3x+4 (this means all real nubers are solutions)
Sub values a=3 b=-6 c=8 in quadratic formula and solve for x
