Answer:

Step-by-step explanation:

All you have to do it first add f(x)+ g(x) and then plug in x=5.

(f+g) = f(x) + g(x)

= (7x- 2) + (9x-4)

= 7x - 2 + 9x - 4

= 16x - 6

(f + g)(5) = 16(5) - 6

= 80 - 6

= 74

71797+3269=75066

75066-2500=72566

72566+0.52=72566

Perform the indicated computation. Write the answer in scientific notation. 12x10^4\3x10^−2

Paul [167]

Let us consider the given expression:

$\frac{12 \times 10^{4}}{3 \times 10^{-2}}$ in the scientific notation.

= $\frac{12 \times 10^{4} \times 10^{2}}{3 }$

[Using the law of exponents, which states

$a^{m} \times a^{n} = a^{m+n}$ ]

= $\frac{12 \times 10^{6}}{3}$

On dividing, we get

= $4 \times 10^{6}$

Hence, it is the required scientific notation of the given expression.
