The first set of parentheses is unnecessary, so just drop it.
The second set of parentheses has a negative sign to its left.
To simplify the second set of parentheses, change every sign inside the parentheses. Then combine like terms.
<span>(–x – 2) – (4x + 3) =
= - x - 2 - 4x - 3
= -x - 4x - 2 - 3
= -5x - 5

Answer:
Y=2/3x-14/3
Step-by-step explanation:
If you subtract the 2 from the y+2 and from the simplified version of 2/3(4), you get the answer above! I hope this helps!
Answer:
? = 40
Step-by-step explanation:
8×(40+7) is exactly the same as 8×40 + 8×7
The given term is:
Since here, the numerator i.e.
cannot be factorized.
SO, the only excluded value is found on the basis of the denominator. The denominator should not be equal to 0, otherwise, the fraction will turn out to be zero.
SO, if y
-4, then denominator will not be zero.
Therefore, the excluded value is -4
Answer:
9) 496 cubic unit
10)10.94
Step-by-step explanation:
in question 9, req volume will be (volume of cube of lenght 10 - that of hole)
hole can be divided into 5 parts,in which 4 have same dimension 6×6×2,and middle part is cube of dimension 6×6×6, total volume will be 4(6×6×2)+6×6×6
=504 cubic.unit
volume of larger cube is 10×10×10=1000 cubic unit
req answer is 1000-504 cubic unit
=496 cubic unit.
10) the ant should walk diagonally to cover minimum distance to reach from A to B, the shortest distance will be when the ant cover the height of lenght 2,then diagonally btwn 4×8, i.e, by using Pythagorean theorem √(16+64)=8.94
now total will be 8.94+2=10.94, it's the shortest possible distance so far!
I'll update each part after solving... wait!
