5^4 power. We can identify this because 5 is multiplying itself 4 times.

Hope this helps!

Answer:

$(f\cdot g)(x)=2x^2+10x+12$

$(f-g)(x)=-x-1$

$(f+g)(1)=10$

Step-by-step explanation:

$\tt f(x)=x+3$

$\tt g(x)=2x+4$

$(f\cdot g)(x)=f(x)\cdot g(x)=(x+3)(2x+4)=2x^2+4x+6x+12$

$=2x^2+10x+12$

$(f-g)(x)=f(x)-g(x)=x+3-(2x+4)=x+3-2x-4$

$=-x-1$

$(f+g)(1)=f(1)+g(1)=1+3+2(1)+4$

$=4+2+4=10$

Solve the equation 4x^2-12x=7 algebraically for x.

ss7ja [257]

  4x² - 12x = 7
  - 7 - 7
4x² - 12x - 7 = 0
  4x² + 2x - 14x - 7 = 0
2x(2x) + 2x(1) - 7(2x) - 7(1) = 0
  2x(2x + 1) - 7(2x + 1) = 0
  (2x - 7)(2x + 1) = 0
2x - 7 = 0 or 2x + 1 = 0
+ 7 + 7   - 1 - 1
2x = 7 2x = -1

x = 3¹/₂     or     x = ⁻¹/₂
