Answer:
b
Step-by-step explanation:
(x - 4) (x - 3)
x^2 - 3x - 4x + 12 (you distribute x in (x-4) to each of the terms x and -3 and multiply them. x*x is x^2 and x*(-3) is -3x. Then, you distribute -4 in (x-4) to each of the terms x and -3 and multiply them. -4*x is -4x and -4*-3 is 12)
x^2 - 7x + 12 (B)
Answer:
x^12 y^2 z^11
a= 12
b= 2
c= 11
Step-by-step explanation:
On the numerator you distribute the exponent 3 to the other exponents.
I think you multiply the 3 so you would get: x^15 y^3 z^12.
so it looks like x^15 y^3 z^12 / x^3yz
Then you subtract the top exponents from the bottom exponent because when you are dividing you subtract exponents. the exponent for y and z in the denominator is 1
and thats how i got x^12 y^2 and z^11. The exponents are a b and c
I hope that is right
The solution is 25% acid, which means 2.5 liters acid (10 x .25).
<span>you need that 2.5 liters to be 10%, or 1/10th the total. </span>
<span>the total would have to be 25 liters (2.5 x 10) so when you add to 10 to get 25 you get </span><span>15 liters. Hope I helped!</span>
Answer:
Solutions given:
Velocity ratio V.R =5
effort =500N
efficiency =80%
magnitude of load=?
mechanical advantage [M.A ]
we have
efficiency =M.A/V.R*100%
80=M.A./5*100
80/100*5=M.A
M.A.=4
again
we have
M.A =load/effort
4=load/500
load=500*4
load=2000N
<h3>
<u>the magnitude of the load is 2000N</u>.</h3>
Calculation = 20/10
Number of cupcakes Victor makes = 20
He puts them in equal rows:
Each row contains = 10 cupcakes
To know the number of rows he placed the 20 cupcakes,
we would divide 20 by 10
Calculation = 20/10
The number of rows of cupcakes Victor makes = 2
