440 x 10 = 4,400. Yes 4,400 is 10 times as much as 440
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)

exponents
c^0.5
so 0.5=1/2 and if you have
x^(z/t)=
![\sqrt[t]{x^z}](https://tex.z-dn.net/?f=%20%5Csqrt%5Bt%5D%7Bx%5Ez%7D%20)
so
c^1/2=
![\sqrt[2]{c^1} or \sqrt{c}](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7Bc%5E1%7D%20or%20%20%5Csqrt%7Bc%7D%20%20)
so
multiplication
-9 times √c is the answer or more commonly written as
-9√c
