Answer:12
Step-by-step explanation: First you put 48 in the house then you put 4 on the outside . First you have to decide how many times 4 goes into 4 which is 1 then you have to subtract by that same number after that you bring down your next number which would be 8 so 4 goes into 8 2 times so then you have to multiply 4x2 which gives you 8 so you subtract and end of with zero . To check your answer multiply 12 and 4
Answer:
find the difference. find the sum
Step-by-step explanation:
The figure is a parallelogram so the facing sides have equal size which means :
DE = GF & DG = EF
-------------------------------------------------------------
DE = 3x - 1 , GF = 2x + 11
DE = GF ==》 3x - 1 = 2x + 11
subtract sides minus 2x
==》- 2x + 3x - 1 = - 2x + 2x + 11
collect like terms
==》 x - 1 = 11
add sides 1
==》 x - 1 + 1 = 11 + 1
==》 x = 12
-------------------------------------------------------------
As we found : DG = EF
DG = 2x - 3 So EF = 2x - 3
To find the size of EF, we need to put the value of x (which we found above) instead x.
EF = 2 × ( 12 ) - 3 ==》 EF = 24 - 3
==》 EF = 21
And we're done...
Answer: 16875x³-13500x²+3600x-320
Step-by-step explanation:
[gοfοh](x) means g(f(h(x))). So you plug in h(x) into f(x) and that into g(x).
f(3x)=5(3x)-4=15x-4
g(f(3x))=5(15x-4)³
g(f(3x))=5(3375x³-2700x²+720x-64)
g(f(3x))=16875x³-13500x²+3600x-320
