Answer:
(4d - 3e)(10d - 3e)
Step-by-step explanation:
(4d - 3e)² + 6d(4d - 3e) ← factor out (4d - 3e) from each term
= (4d - 3e)(4d - 3e + 6d) ← collect like terms inside parenthesis
= (4d - 3e)(10d - 3e)
Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.
33-23=10. 10+23=33. 23-10=13
the numbers are 23 and 10
Answer:
The other sides equal 9cm also because a square has four equal sides.
L=9cm * W=9cm =A
A=81 cm
Let the four consecutive numbers be x,x+1,x+2,x+3.
Now the product of second and third number=(x+1)(x+2)=x²+3x+2=k
Product of first and fourth number=x(x+3)=x²+3x=k-2
A.T.Q
product of second and third number= product of first and fourth number+2
Hence proved
