Answer:
yes
Step-by-step explanation:
–2.5 is greater than –3, because –2.5 lies to the right of –3 on the number line.
Answer:
28 degrees
Step-by-step explanation:
Because a triangle equals 180, you can subtract 90 and 34 from triangle ABE to leave you with 56 degrees for angle B.
Since CBA is a straigth line with 180 degrees, you can subtract 56 to end up with 124 degrees for angle CBE.
Since line BD bisects angle EBC (splits in half), you can divide the 124 degrees into 62 degrees.
Now that we know angle CBE equals 62 degrees, we can add the 90 degrees and subtract them from the 180 degrees of the triangle.
62+90=152
180-152=28
It’s really hard to see :(
Note that 125 = 5³. Make use of the factorization of the sum of cubes:
a³ +b³ = (a+b)(a² -ab +b²) . . . . . . a formula worth keeping handy
Then ...
_____
When x=-5, this evaluates to
... (-5)²-5(-5) +25 = 75
