Answer:
d. 7 × (10 + 9) = (7 × 10) + (7 × 9)
Step-by-step explanation:
The format of writing numbers in distributive property is a(b+c) = (a×b)+(a×c)
We can see that in choice d. 7 × (10 + 9) = (7 × 10) + (7 × 9) it is in correct format of writing numbers in distributive property. Thus, choice d. is correct.
Verification:-
a(b+c) = (a×b)+(a×c)
7 × (10 + 9) = (7 × 10) + (7 × 9)
Let
x------> the number of pink roses bushes
y----> the number of white rose bushes
we know that
-----> equation A
substitute the value of x in the equation A
y-1+ 2y^2/y^3+1
6.3 inches
5/9 = 3.5/x
5x = 31.5
x = 6.3
