3 5/8 or three and five over eight
George's father will be 80 years old when George is half his age.
<span>Half his age is 50 so 35 + 15 is 50 so add that to his dads age
</span>
Answer: 80 years old
Answer:
The second and third line are wrong
Step-by-step explanation:
(4x³ +4x²-8x) -(8x²-16x+4)
= 4x³ +4x²-8x - 8x²+ 16x -4
= 4x³ +4x²- 8x²-8x+ 16x -4
= 4x³ -4x²+ 8x -4
In the second line:
it has to be +16x because - times - is +
it is like -1*(8x²-16x+4)
In the third line:
you can only add or subtract the xs with the same exponentation, so
4x²- 8x² and -8x+ 16x
4x²- 8x²= -4x² not +12x²
Answer:
38 inches
Step-by-step explanation:
since we are finding the diagonal we are going to use the equation a^2+b^2=c^2
so if we do substitution we would have 32^2+20^2=C^2
32^2= 1024
20^2= 400
so,
1024 + 400 = C^2
1424 = C^2
to get rid of the C^2 we have to take the square root of it. But whatever we do on one side of the equation we have to do on the other side so,
C = sqrt(1424)
C = 37.73
C = 38 inches
Answer:
StartFraction 42 Over n EndFraction minus 8; when n = 6 the expression equals –1
Step-by-step explanation:
Let's put the equation into numbers:
“8 less than the quotient of 42 and a number”
= 42/n - 8
Now, substitute 6 into this expression:
42/6 - 8
= 7 - 8
= -1
