Option A:
I and III only the answers.
Solution:
Let white vases be "w" and red vases be "r".
Cost of total flower = $336
Cost of each vase = $11
Total cost of the centerpieces
= Cost of (white vases + red vases) + Cost of flowers
= 11(w + r) + 336
= 11w + 11r + 336
Total cost of the centerpieces = 11w + 11r + 336 = 11(w + r) + 336
Therefore I and III only the answers.
Option A is the correct answer.
Your answer is D for your purposes
Work:
Multiply b and 5
Multiply b and 1
The b just gets copied along.
5*b evaluates to 5b
Multiply b and 6
Multiply b and 1
6*b evaluates to 6b
6*b-10 evaluates to 6b-10
Multiply 5b by 6b-10
Multiply 5b by each term in 6b-10 term by term.
This is the distributive property of multiplication.
Multiply 5b and 6b
Multiply the b and b
Multiply b and b
Combine the b and b by adding the exponents, and keeping the b, to get b²
5b × 6b =
Multiply 5b and -10
Multiply b and 1
5b × -10 = -50b
5*b*(6*b-10)
***The final answer is 30b²-50b***
Answer:
d. x^5(x^2 - 1)
Step-by-step explanation:
x^7 - x^5
Factor out x^5
x^5(x^2−1)
Consider x^2−1. Rewrite x^2−1 as x^2−1^2. The difference of squares can be factored using the rule: a^2 - b^2 =(a−b)(a+b).
(x−1)(x+1)
Rewrite the complete factored expression.
x^5(x−1)(x+1)
Simplify.
(x^2 - 1)x^5
Swap terms to the left side.
x^5(x^2 - 1)
Answer:
10 C
Step-by-step explanation:
10 trees / 2 hours = 5 trees per hour
150 trees / 5 per hour = 30 hours
