(-2d² + s)(5d² - 6s)
Simplify.
(-2d² × 5d²) + (-2d² × 6s) + (s × 5d²) + (s × -6s)
Simplify.
-10d² + (-12d²s) + (5d²s) + (-6s²)
Take out the parenthesis.
-10d² - 12d²s + 5d²s - 6s²
Combine like terms.
-10d² + (-12d²s + 5d²s) - 6s²
Simplify.
-10d² - 7d²s - 6s²

This is asking what is z and y, so you must know that a triangle is 180 degrees, so if it is 180 degrees, than all three angles that the triangle has must add up to 180 for every single triangle for it to be a triangle. So you have 45 degrees and 47 degrees, which adds up to 92 degrees, so in order to find y you need to subtract 92 from 180, which is 88. 88 is the missing number, and the missing number in this triangle is y, so y= 88 degrees. This can fool you because it looks like 90 degrees, but it is actually 88. Z is a little trickier, because y isn't 90 degrees, if it was than z would be a direct reflection of y, but it isn't, so we must find the exact angle for this variable. I see it like this, if y is 88, than it is smaller than 90 obviously, so it is acute. If that line keeps going down, than really z would be bigger than y, because that line is going down but it is so hard to tell. So if y is smaller by 2 degrees, than z would be bigger by 2 degrees, meaning that z is 92 degrees, since it is slowly decreasing. Hope this helps
NO. Three congruent angles only proves the triangles are similar. You must have at least one side length to prove congruency.
SSS, SAS, ASA, AAS prove triangle congruency.
Answer: C
Answer:
18 boys and 15 girls
Step-by-step explanation:
Since the ratio is 6:5 and there are 18 boys, you do 18/6=3
Then you do 5*3=15
Answer:
2
Number line.
We start at -6 or -8.
If we start from -6, we will be going __ spaces to the left until we get to -8.
Or start from -8 and go __ spaces to the right until you get to -6.
Then count the spaces.
You'll get 2.
