Answer: The second option (160 cm)
Step-by-step explanation:
1. You can obtain the perimeter of a quadrilateral by adding the lenghts of the sides.
2. You know that the ratio of the side lengths is 3:3:5:8 and the perimeter is 380 centimeters.
3. Therefore, you can write the following expression, where x is an integer:

4. Solve for x:

5. Therefore, the longest side is:
(160 cm)
You can’t do this. That’s is not mathematically correct
Answer:
149
Step-by-step explanation:
If the expression 3x+10 is equal to 6 for some value of x, then what is the value of 3x+2 equal to for the same value of x ?
The answer is B, or y - 6 = 3/4 (x - 4). To put (-4, 6); m = 3/4 in point-slope form, you first start with the point-slope form equation which is y - k = m (x - h). The ordered pair that it wants you to put in is (-4, 6). To figure out where the ordered pair goes, you replace the variables (h, k) with (-4, 6). The h will always be the point on the
x-axis and the k will always will be the point on the y-axis. Putting these together, you now get y - 6 = m (x - 4). As the same in slope-intercept form, or y=mx+b form, the slope in this equation is m. In this equation, m = 3/4. So, the equation in point-slope form is y - 6 = 3/4 (x - 4).
First off, you must have a calculator to find any cos,sin, or tan.
tangent of 39 degrees is .80978
rounding to the nearest ten thousandth would be .8098 because the 8 in the hundred thousandths is greater than 5.
