Answer:

x = -1/2 or x = -3

Step-by-step explanation:

2x^2 + 7x + 3 = 0

First, we try factoring the polynomial.

(2x + 1)(x + 3) = 0

It works. Now we set each factor equal to zero.

2x + 1 = 0 or x + 3 = 0

2x = -1 or x = -3

x = -1/2 or x = -3

What’s all input for f(x)=3

defon

Answer:

all inputs are equal to 3

Step-by-step explanation:

$f(x) = 3 \\ = 3 \times 1\\ = 3 \times {x}^{0} \\ anything \: raised \: to \: 0 \: is \: 1 \\$

$\\ substituting \: any \: value \\ \: of \: x \: in \: f(x) \\ f(3) = 3 \times {3}^{0} \\ = 3 \times 1 \\ = 3 \\$

$\\ similarly \: all \: values \: of \: x \: will \\ give \: 3$

a cardboard box holds 31.25 cubic inches of creamy butter. The butter is molded into a square prism that is 5 inches long. How m

lesya [120]

Answer:

$62.5 \:in^2$

Step-by-step explanation:

Volume of the butter in the cardboard = 31.25 cubic inches

Length of the Molded Square Prism =5 Inches

Let the length of the square cross sectional area = x

Volume of the Prism $=x^2l$

Since l=5 Inches

$5x^2=31.25\\x^2=6.25\\x=2.5\: Inches$

Next, we determine the surface area of the New Cardboard box to be made.

Length of the Cardboard Box=5 Inches

Length of the square cross sectional area = 2.5 Inches

Total Surface Area $=2(x^2+xl+xl)=2(x^2+2xl)$

$=2(2.5^2+2(2.5)(5))\\=2(6.25+25)\\=2*31.25\\=62.5 \:in^2$

Therefore, $62.5 \:in^2$ of cardboard is needed,
