I think u should check the first one again u made a mistake but the second one is correct if u need any more help ask me
Step-by-step explanation:
in moving from the point let say A(7,0) to the point B(-1,3), the x-coordinate increases by (7-(-1)= 8 while the y-coordinate decreses by (0-3)=-3. The same of this is given by finding the square of 8=64 and (-3)=9. by summing the two we have 64+9=73. so we find the square root of 73 which which is 8.55. so therefore the answer is 8.55 which is approximately 9
Consecutive integers are 1 apart
x,x+1,x+2
(x)(x+1)(x+2)=-120
x^3+3x^2+3x=-120
add 120 to both sides
x^3+3x^2+3x+120=0
factor
(x+6)(x^2-3x+20)=0
set each to zero
x+6=0
x=-6
x^2-3x+20=0
will yeild non-real result, discard
x=-6
x+1=-5
x+2=-4
the numbers are -4,-5,-6
use trial and error and logic
factor 120
120=2*2*2*3*5
how can we rearange these numbers in (x)(y)(z) format such that they multiply to 120?
obviously, the 5 has to stay since 2*5=10 which is out of range
so 2*2*2*3 has to arrange to get 3,4 or 4, 6 or 6,7
obviously, 7 cannot happen since it is prime
3 and 4 results in in 12, but 2*2*2*3=24
therfor answer is 4 and 6
they are all negative since negaive cancel except 1
the numbers are -4,-5,-6
Yes use inverse to get the correct answer
Answer:
(ab)/9
Step-by-step explanation:
The product of a and b is written ...
ab
Division by 9 is indicated by a fraction with 9 in the denominator and the dividend in the numerator. In text form, it looks like ...
(ab)/9
In typeset form it looks like ...
The parentheses are necessary in both cases if you want to make sure the product is formed before the division occurs. The Order of Operations requires that the contents of parentheses be evaluated first.
On the other hand, in text form, ab/9 is supposed to be evaluated left to right, so the multiplication should occur before the division. (There is no "left to right" for the typeset fraction in the case where there are no parentheses.)

<em>Comment on the question</em>
Technically speaking, There is no way to write the expression so that the multiplication is required before the division, because the associative and commutative properties of multiplication allow the sequence to be rearranged to any convenient order.
