for the expression to give a positive results then x just be a negative number
or zero
x<=0
Answer:
x = 7.3
Step-by-step explanation:
When solving for missing sides using angles, use trig functions.
We have the angle 63° to use.
We are given the hypotenuse of the triangle, as well as the side adjacent to the angle, so we can use the cos function.
Cos T = (adjacent side)/(hypotenuse)
Here we know 'T' and the hypotenuse, so plug them in and solve
Cos 63° = x/16
(16)Cos 63° = x (multiply both sides by 16 to isolate 'x')
7.263847996 = x (use your calculator to solve the left side)
7.3 = x (rounded to the nearest 10th)
Answer:
539
Step-by-step explanation:
We have x^(-4) • x^(7).
This leads to x^(-4 + 7).
Work out the math inside the parentheses.
ANSWER: x^(3).

Answer:
E and D
Step-by-step explanation:
The area of a rectangle is length x width. In this case, that's (12+s) x 1/3
This can be re-written as 1/3(12+s)
D is 1/3s + 4 which is what happens when you multiply 1/3 by 12 which = 4 and multiply 1/3 by s which = 1/3s. So the answer is 1/3s+4.
