Guessing these are the options:
4 + (-8) ___ 6 + (-8) + (-6)
If the signs are the same, you add. If you have one positive and one negative sign, you minus:
4 + (-8) = 4 - 8 = -4
6 + (-8) = 6 - 8 = -2
(-2) + (-6) = (-2) - 6 = -8
-4 ___ -8
<h2>-4 > -8</h2>
Answer:
21a + 17b
Step-by-step explanation:
To simplify, we need to distribute the 9 to the terms inside of the parentheses that it is being multiplied by and 4 to the terms inside of the parentheses that it is being multiplied by like so:
9(a)+9(b)+4(3a)+4(2b)
9a+9b+12a+8b
Add like terms
21a + 17b
4 out of 10 because you add 1 +3 that equals 4 and then add6+4=10=4 out of10
It says describe the perimeter with your own words, so what perimeter?
Recall that using the pythaogorean theorem, which is only for right-triangles, the longest leg squared is the sum of the other two squared, namely c² = a² + b², now, if those units above are of a right triangle, then 25² = 7² + 24².
do they check out? if they do, then yes, you can make a right-triangle, if not, they nope.
