The distributive property "distributes" a number through all numbers/terms in a set of parentheses by multiplication.
EXAMPLES
Equivalent expressions are the first and last steps. The middle step just shows the work.
5(2 + 3x)= (5*2) + (5*3x)= 7 + 15x
4(2x + 4y)= (4*2x) + (4*4y)= 8x + 16y
10(4x + 5)= (10*4x) + (10*5)= 40x + 50
ANSWER:
Only one pair below is needed for your answer.
5(2 + 3x)= 7 + 15x
4(2x + 4y)= 8x + 16y
10(4x + 5)= 40x + 50
Hope this helps! :)
Answer: x^2+8x+16
Step-by-step explanation:
Following (a+b)^2=a^2+2ab+b^2,
(x+4)^2=x^2+2(4x)+(4)^2
x^2+8x+16
Answer:f=1800/d Inverse proportion function. Provided f is in pounds & d is in inches.
Step-by-step explanation: the relationship between f & d is inverse proportion.
A constant k has to be derived from the relationship.
If f is inversely proportional to d then f=k(1/d)
K= f X d
= 50 X 36
=> constant K=1800.
