Answer:

<h3>\boxed{ \huge{ \boxed{ \bold{ \sf{26 {x}^{2}  + 22x + 25}}}}}</h3>

Step-by-step explanation:

\sf{(19 {x}^{2}  + 12x + 12) + ( {7x}^{2}  + 10x + 13)}

Remove the unnecessary Parentheses

⇒\sf{19 {x}^{2}  + 12x + 12 + (7 {x}^{2}  + 10x + 13)}

When there is a ( + ) in front of an expression in parentheses , the expression remains the same

⇒\sf{19 {x}^{2}  + 12x + 12 + 7 {x}^{2} + 10x + 13}

Collect like terms

⇒\sf{26 {x}^{2}  + 22x + 12 + 13}

Add the numbers

⇒\sf{26 {x}^{2}  + 22x + 25}

Hope I helped!

Best regards!

Answer:

26x^2+22x+25

Step-by-step explanation:

We remove the brackets, getting 19x^2+12x+12+7x^2+10x+13.

We then combine like terms, getting (19+7)x^2+(12+10)x+(12+13).

As a result, we get 26x^2+22x+25.

Nancy is making lemonade for her birthday party. She made 6 batches. Each batch of lemonade uses 24 fluid ounces of lemon juice
Goryan [66]

Answer:

Step-by-step explanation:

1 Us pint = 16 Us fluid ounces

It means that 8 pints of water would be

8 × 16 = 128 fluid ounces

Each batch of lemonade uses 24 fluid ounces of lemon juice and 8 pints of water. The total number of fluid ounces in each batch is

128 + 24 = 152 fluid ounces

Also,

1 fluid ounce = 0.125 Us cups

Therefore, the number of cups made is

152 × 0.125 = 19 cups

If each serving is 1 cup, then the number of servings that she made from each batch of lemonade is 19

servings. The number of batches made is 6. Therefore, the number of servings made altogether is

6 × 19 = 114

If her brother came and spilled half of it on the floor, then the number of servings that she have left after that for her party is

114/2 = 57 servings

Snow cone holders are sold in sleeves of 50. How much paper is needed for each sleeve if the cones have a slant height of 5 inch
Genrish500 [490]

Answer:

The correct answer is

Step-by-step explanation:

Snow cone holders are sold in sleeves of 50.

The cones have a slant height (l) of 5 inches and a radius (r) of 3 inches.

Surface area of each cone holder = π × r × l = π × 15 = 15π square inches.

Surface area of all 50 cones in the sleeve = 15π × 50 = 750π = 2357.143 square inches.

Thus 2357.143 square inches pf paper would be necessary for each sleeve each having 50 cone holders.

Please help!! Write in simplest radical form: √7/8 Show how you figured it out
12345 [234]

Given expression: \sqrt{\frac{7}{8}}.

\mathrm{Apply\:radical\:rule\:}\sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}}

=\frac{\sqrt{7}}{\sqrt{8}}

\sqrt{8}=\sqrt{2^2\cdot \:2}=2\sqrt{2}

\frac{\sqrt{7}}{\sqrt{8}} =\frac{\sqrt{7}}{2\sqrt{2}}

\mathrm{Rationalize\:}\frac{\sqrt{7}}{2\sqrt{2}}

\mathrm{Multiply\:by\:the\:conjugate}\:\frac{\sqrt{2}}{\sqrt{2}}

=\frac{\sqrt{7}\sqrt{2}}{2\sqrt{2}\sqrt{2}}

=\frac{\sqrt{14}}{4}

=\frac{\sqrt{14}}{4}.
