1/2(4+X)+2=16
2+(0.5 x X) + 2 = 16
4 + (0.5 x X) = 16
0.5 x X = 12
X = 24
idk if u understand my working out - message me if u dont
hope it helped tho :)
The answer to this question is 39.28; 65.12
Answer:
f(x) = x⁴-6x³-13x²+66x+72
Step-by-step explanation:
Factors are: (x+3)(x+1)(x-4)(x-6)
[(x+3)(x+1)][(x-4)(x-6)]
[x²+3x+x+3][x²-4x-6x+24]
(x²+4x+3)(x²-10x+24)
x⁴+4x³+3x²-10x³-40x²-30x+24x²+96x+72
f(x) = x⁴-6x³-13x²+66x+72
Answer:
it is 5 inches squared
Step-by-step explanation:
A=48
b=144
c=-84
First, you simplify the second equation by multiplying 6 to 2x and 6 to 7. Then, you get the two equations, (4x-2) times (12x+42). You then use the FOIL method, multiplying 4x to 12x, 4x to 42, -2 to 12x, then -2 to 42. Simplify. Then number before x squared is your a value, value before x is b, and the value without x is c.
