im pretty sure you multiply 12 by 46 so that would be $552 for the week
The measure of YZ is 3.4 cm and the measure of c is 1.7 cm.
Given that, Y is between X and Z. XY = 5.5 , YZ = 2c , X Z= 8.9.
We need to find the value of c and YZ.
<h3>What is a line segment?</h3>
A line segment is a part of a line that has two endpoints and a fixed length. It is different from a line that does not have a beginning or an end and which can be extended in both directions. In this lesson, we will learn more about a line segment, its symbol, and the way to measure a line segment.
Now, YZ=XZ-XY
⇒2c=8.9-5.5
⇒2c=3.4 cm
⇒c=1.7 cm
Therefore, the measure of YZ is 3.4 cm and the measure of c is 1.7 cm.

Answer: All of them can be a triangle except for #11 because the two shortest sides don't add up to more than the longest side.
#10 is a Pythagorean Triple so it is a right triangle.
To determine if the triangle is an acute or obtuse triangle, we just need to plug the values into the Pythagorean Theorem. If the sum of the legs squared is greater than the hypotenuse, it's an acute triangle. If the sum of the legs square is less than the hypotenuse, it's an obtuse triangle.
Using this logic, 7 & 12 will be obtuse while 8 & 9 will be acute.
Answer:x=-0.75
Step by step: 4 to 2nd power multiple 4 by 4 you get 16 so (-8x-6)16 multiply 16 to -6 and -8x and so on...
