Answer:

x = -6.00 (rounded to nearest hundredth)

Step-by-step explanation:

for a quadratic equation, $h(x)=ax^2+bx+c$
we have $f(x)=x^2+12x+31.5$
a = 1
b = 12
to find minimum use equation $x=\frac{-b}{2a}$

$x=\frac{-b}{2a}\\x=\frac{-(12)}{2(1)}\\x=\frac{-12}{2}=-6$

Troyanec [42]

Answer:

Measure of segment JL is 20 cm.

Step-by-step explanation:

By applying geometric mean theorem in the given right triangle,

$\frac{JM}{KM}=\frac{KM}{ML}$

$(KM)^2=(LM)(ML)$

$8^2=(JM)(4)$

$JM=\frac{64}{4}$

$JM=16$

Since, $JL=JM+ML$ [By segment addition postulate]

$JL=16+4$

$JL=20$ cm

Therefore, measure of segment JL is 20 cm.

Giving BRAINLIEST for correct awnser. Select the two binomials that are factors of 64x^2 - 36.

eimsori [14]

Answer:

B. 8x - 3

C. 8x + 12

Step-by-step explanation:

64 is a perfect square, meaning it has two factors that are identical (8), and 36 is also a perfect square, but in this case, you don't see two 6's in the answer choices.

12 and -3 give you a product of -36, so your answer choices would be:

(8x - 3) (8x + 12)

If you're unsure, you can multiply them together to check if they come out to the unfactorized expression.

A company manufactures skateboards. Each skateboard requires 1 6/7 hours of labor to assemble and 2 1/2 hours of labor to finish

Assoli18 [71]

Answer: The total cost will be $156.85.

Step-by-step explanation:

Since we have given that

Time taken by labor to assemble the each skateboard is given by

$1\frac{6}{7}\ hours\\\\=\frac{13}{7}\ hours$

Time taken by labor to finish and stain each skateboard is given by

$2\frac{1}{2}\ hours\\\\=\frac{5}{2}\ hours$

Cost of labour to the company per hour = $36.00

According to question,

We will use "Distributive Property":

$a\times (b+c)=a\times b+a\times c$

$36(\frac{13}{7}+\frac{5}{2})\\\\=36\times \frac{13}{7}+36\times \frac{5}{2}\\\\=\frac{468}{7}+18\times 5\\\\=\frac{468}{7}+90\\\\=\frac{468+630}{7}\\\\=\frac{1098}{7}\\\\=\$156.85$

Hence, the total cost will be $156.85.
