Answer:
Step-by-step explanation:
the first step in factorising is to look for any common factors.
27
and
36
are both multiples of
3
9
.
We use
because it is the highest common factor:
Divide
out of each term:
27+36x=9(3+4x)
The reverse process would be to use the distributive law to multiply each term in the bracket by
This will give us the original expression:
9(3+4x)=27+36x
9(4x+3) :)
prism B is greater
prism A
lenght: 1×4=4
width: 4×8=32
height: 8×1=8
add them all up and multiply it by 2 = 4+32+8×2=52
prism B
lenght: 10×2=20
width: 2×1.5=3
height:1.5×10=15
add them all up and multiply it by 2= 20+3+15×2=76
