Answer:
Step 1 is incorrect.
Step-by-step explanation:
The given expression is :
In step 1, Deepak rearranged the terms in order to simplify like terms together that is followed in step 2.
o, rearranging of the terms of an expression is commutative property and not distributive property. The distributive property is generally applicable to multiplication and is given as:
The commutative property is given as:
x+y = y +a
Therefore, adding terms by changing their order is commutative property of addition and not distributive property. Step 1 instruction is wrong.
Answer:
178.3 mm²
Step-by-step explanation:
Surface area = Base area + 3 x side triangles area
Sₐ = 43.3 + 3 x (1/2 x (10 x 9)) = 43.3 + (3 x 45) = 178.3
Answer:
Step-by-step explanation:
You need to add $6.50 and $11.75 and you get $18.25.
Answer: 350,340,330,320,310,300,290,280,270,260,250,240.
Step-by-step explanation:
To solve this exercise you must keep on mind the following information:
1. By definition skip counting is about counting by a number which is not the number 1.
2. Skip counting by ten from 350 to 240 means that you need to subtract 10 to a number to find the other one.
3. Therefore, you must subtract 10 to 350 and then you need to do this over and over again until you get 240.
