$\text{Use the distributive property:}\\\\a(b+c)=ab+ac$

$2(x+5)+3(x^2-5x+13)=(2)(x)+(2)(5)+(3)(x^2)-(3)(5x)+(3)(13)\\\\=2x+10+3x^2-15x+39=3x^2-13x+49$

Question:

A customer buys bouquets of tulips and bouquets of roses for $40.25. The bouquet contained 17 tulips and cost $18.25. What is the price of a bouquet of roses?

Answer:

$Rose =\$22.00$

Step-by-step explanation:

Given

$Total = \$40.25$

$Tulips = \$18.25$

Required

The cost of a bouquet of roses

Since the customer bought a bouquet each, the formula to use is:

$Total = Tulip + Rose$

Make Rose the subject

$Rose =Total - Tulip$

$Rose =\$40.25 - \$18.25$

$Rose =\$22.00$

<em>A bouquet of rose costs $22.00</em>

snow_lady [41]

Answer:

Step-by-step explanation:

If diameter is 14 inches radius = d/2 = 14/2 = 7 inches

Circumference = 2 pi R = 2 × 22/7 × 7

= 44 inches

Area = pi R square = 22/7 × (7)^2

=22/7 × 49

= 154 inches

Factor the expression completely.

evablogger [386]

Answer:

Factoring the expression $xy^4+x^4y^4$ completely we get $\mathbf{xy^4(x+1)(x^2-x+1)}$

Step-by-step explanation:

We need to factor the expression $xy^4+x^4y^4$ completely

We need to find common terms in the expression.

Looking at the expression, we get $xy^4$ is common in both terms, so we can write:

$xy^4+x^4y^4\\=xy^4(1+x^3)$

So, taking out the common expression we get: $xy^4(1+x^3)$

Now, we can factor the term (1+x^3) or we can write (x^3+1) by using formula:

$a^3+b^3=(a+b)(a^2-ab+b^2)$

So, we get:

$xy^4(1+x^3)\\=xy^4(x^3+1)\\Applying\:the\:formula\;of\:a^3+b^3\\=xy^4(x+1)(x^2-x+1)$

Therefor factoring the expression $xy^4+x^4y^4$ completely we get $\mathbf{xy^4(x+1)(x^2-x+1)}$
