Answer:
9x^2 and -30x
Step-by-step explanation:
Basically, what we want to do is expand out (3x - 5)^2, which is the same as (3x - 5)(3x - 5).
Use FOIL (first, outer, inner, last):
- the first terms are 3x and 3x, so multiply those together: 3x * 3x = 9x^2
- the outer terms are 3x and -5, so multiply those: 3x * (-5) = -15x
- the inner terms are -5 and 3x, so multiply those: (-5) * 3x = -15x
- the last terms are -5 and -5, so multiply those together: (-5) * (-5) = 25
Add all these together:
9x^2 + (-15x) + (-15x) + 25
9x^2 - 30x + 25
The missing terms are thus 9x^2 and -30x.
Answer:
Step-by-step explanation:
<u>Points given:</u>
<u>Partition ratio: </u>
<u>Formula for the point:</u>
- x = x1 + a/(a+b)×(x2 - x1)
- y = y1 + a/(a +b)×(y2 - y1)
<u>So the points are:</u>
- x = 3 + 5/(5+3)×(7-3) = 3 + 5/8×4 = 5.5
- y = -3 + 5/8×(5 - (-3)) = -3 + 5/8×8= 2
Answer:
The answer is 170.6 cubic mm
Step-by-step explanation:
The answer would be A. The triangle with the 70 seems to be isosceles and that means that two of the angles equal 70. 70+70=140. Subtract 140 from 180 to find the third angle because every triangle has a total of 180 degrees. Due to the fact that x and the 40 degrees are on the same line, they will equal 180 degrees. So, 180-40=140. X=140. I hope this helps
