Answer:

3x³ + 5x² + 4x + 4

Step-by-step explanation:

Given

(x + 2)(x² + x + 2) + 2(x³ + x²)

To expand the product, each term in the second factor is multiplied by each term in the first factor, that is

x(x² + x + 2) + 2(x² + x + 2) + 2(x³ + x²) ← distribute the parenthesis

= x³ + x² + 2x + 2x² + 2x + 4 + 2x³ + 2x² ← collect like terms

= 3x³ + 5x² + 4x + 4

Answer: 2 servings of Gerber Mixed Cereal for Baby and 3 servings of Gerber Mango Tropical Fruit Dessert .

Step-by-step explanation:

Let x be the number of servings of Gerber Mixed Cereal for Baby and y be the number of servings of Gerber Mango Tropical Fruit Dessert .

By considering the given information, we have the following two equations:_

$60x+80y=360-----(1)\\\\11x+21y=85------(2)$

Divide 20 on both the sides on Equation (1) , we get

$3x+4y=18------(3)$

Multiplying 11 on both the sides in (3), we get ,

$33x+44y=198------(4)$

Multiplying 3 on both the sides in (2), we get ,

$33x+63y=255------(5)$

Now, subtract equation (1) from (2), we get

$19y=57\\\\\Rightarrow\ y=\dfrac{57}{19}=3$

Substitute Y in (3), we get

$3x+4(3)=18\\\\\Rightarrow\ 3x+12=18\\\\\Rightarrow\ 3x=6\\\\\Rightarrow x=2$

Hence, you should you 2 servings of Gerber Mixed Cereal for Baby and 3 servings of Gerber Mango Tropical Fruit Dessert .

Farmer brown has ostriches and llamas. Altogether she counts 98 feet and 33 heads. How many ostriches does she have?

Ronch [10]

Answer: She has 17 ostriches.

Step-by-step explanation:

We know , ostrich has 2 legs where as llama has 4 legs.

Let x be the number of ostriches and y be the number of llamas.

Then, as per given , we have the following linear equations :

$2x+4y=98---(i)\\\\ x+y=33---(ii)$

Multiply 2 to eqn (ii) , we get

$2x+2y=66---(iii)\\$

Subtract (iii) from (i) , we get

$2y=32\\\Rightarrow\ y=16$

Put this in (ii) , we get $x+16=33\Rightarrow\ x=17$

Hence, there are 17 ostriches and 16 llamas.

Can someone please help me?<br> If g(x) = x2 - 5x + 2, find g(0).

Debora [2.8K]

g(x) = x² - 5x + 2

You are looking for g(0). This means that you must replace all the x values in the equation above with 0

(0)² - 5(0) + 2

Now you need to solve according to the rules of PEMDAS:

(0)² - 5(0) + 2

0 - 5(0) + 2

0 - 0 + 2

0 + 2

g(0) = 2

Hope this helped!
