(gºf) means solve f(x) first, then use that for g(x)

In the equation for f(x) replace x with -3:

f(x) = x +4 = -3 +4 = 1

Now replace the x in the equation for g(x) with 1

g(x) = x = 1

68 * 27 - 81 + ? = 600

tankabanditka [31]

The missing term is -1155.

Step-by-step explanation:

Given expression is

68 * 27 - 81 + ? = 600

Let the missing term be x

$68*27-81+x=600\\1836-81+x=600\\1755+x=600$

Subtracting 1755 from both sides

$1755-1755+x=600-1755\\x=-1155$

Therefore,

The missing term is -1155.

What is the length of the diagonal, ddd, of the rectangular prism shown below?

ad-work [718]

Answer:

≈ 9.6 units

Step-by-step explanation:

<em>Refer to attachment</em>

The diagonal d is the hypotenuse of right triangle with sides of 5 and a

The line a is the hypotenuse of the right triangle with the sides of 2 and 8.

<u>So, as per Pythagorean theorem:</u>

d² = 5² + a²
d²= 5² + 2²+ 8² = 25 + 4 + 64 = 93
d² = 93
d = √93
d ≈ 9.6 units (rounded to the nearest tenth)
