13 times 6 times 2.5 equals 195 square inches
The answer is (2x + 4)
explanation:
in this situation you’d have to distribute the 2 all throughout the binomial.
2 times x is 2x and 2 times 2 is 4.
hope it helps!
Answer:D
Step-by-step explanation:
(3x^3 - 5x^2 + 4x - 9)-(7x^3 - 8x^2 - 5x + 10)
open brackets
3x^3 - 5x^2 + 4x - 9 - 7x^3 + 8x^2 +5x - 10
Collect like terms
3x^3-7x^3-5x^2+8x^2+4x+5x-9-10
-4x^3+3x^2+9x-19
Vertical angles are equal, so the angle above 2 is also 88+x. Then, because the 2 sides of the 52° triangle are congruent, the angles beneath them are too. So you are left with the equation of that triangle being...
88 + x + 88 + x + 52 = 180
combine like terms
228 + 2x = 180
subtract 228 from both sides
2x = -48
divide both sides by 2
x = -24
Hope this helps :)
We can do a tree-diagram in order to visualize better the sample space
The sample space has 3x2x2=12 combinations
The combinations are:
{TRM, TRO, TWM, TWO, HRM, HRO, HWM, HWO, DRM, DRO, DWM, DWO}
