Step-by-step explanation: Bill bought 2 cups of coffee for $3 each and 2 muffins for $3 each. he used this expression to calculate the total amount he spent. (2 × 3) + (2 × 3)
What is another expression to calculate the total amount spent?
A) (2 + 2) × 3
B) 2 + (3 + 3)
C) 2 × 3 × 3
D) (2 + 3) × (3 + 2)
The distributive property of multiplication allows you multiply a sum by multiplying each individual added separately and then adding the sum.
Hence, the addenda are 2 cups of coffee and 2 muffins. The multiplier is $3 since both have the same price. This gives the cost of the individual addend and on addition gives the total amount spent.
Vertex form is basically commplete the square y=a(x-h)^2+k
y=x^2+14x+4 take 1/2 of 14 and square it, (7^2=49) add that and its negative to right side y=x^2+14x+49-49+4 factor perfect squaer y=(x+7)^2-49+4 y=(x+7)^2-45
