Answer:
4(90) + 4(2)
Step-by-step explanation:
The given expression is 4(92)
This can be expressed as ![\[4*92\]](https://tex.z-dn.net/?f=%5C%5B4%2A92%5C%5D)
This can also be expressed as ![\[4*(90+2)\]](https://tex.z-dn.net/?f=%5C%5B4%2A%2890%2B2%29%5C%5D)
Using the distributive law of multiplication and additon,
a*(b+c) = a*b + a*c
In this case a=4
b=90 and c = 2
So the equivalent expression is ![\[4*(90)+4*(2)\]](https://tex.z-dn.net/?f=%5C%5B4%2A%2890%29%2B4%2A%282%29%5C%5D)
But this is the same as option 2 in the list of given options.
Hence the equivalent expression is 4(90) + 4(2)
Answer:
b) -4
Step-by-step explanation:
Well your at 2 and going to -2 so on a number line you be going back or left.
Going two left gets you to zero and going two more get you -2. So in total you went back four and that be represented as -4.
The answer is 50
The answer is 50 because it told you that he had 40 seeds with 4 packets and if you add another packet it makes 50 because each packet had 10 in it
We have the equations: l = 2b and 2l + 2b = 228;
Then, 4b + 2b = 228;
6b = 228;
b = 228/6;
b = 38 (breadth);
l = 2·38;
l = 76 (length);
