factor this equation 75k^2+30k=-3

Answers

Answer 1
The answer is K=-1/5

You suppose to divide both sides by 3.

Move the constant to the left-hand side and change its sign Use a^2 + 2 ab+ b^2 = (a+b)^2 to factor the expression.

The only way an exponentiation can be 0 is when the base equals 0.

Move the constant to the right-hand side and change its sign.

Divide both sides of the equation by 5.

Answer: K=-1/5

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The multiplication of 4/7 x 5/6 as a fraction in the simplest form​ is 10/21.

What is multiplication?

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The multiplication of the two fractions 4/7 and 5/6 can be done as,

4/7 × 5/6

Multiply the numerator and the denominator of the two fractions

= (4×5)/(7×6)

= 20/42

Dividing both the numerator and the denominator by 2 to simplify,

= 10/21

Hence, the multiplication of 4/7 x 5/6 as a fraction in the simplest form​ is 10/21.

this is the answer.

The line plot shows the weights of pumpkins available at a farm stand. The pumpkins cost $0.30 per pound. A line plot named "Pumpkin Weights" shows data from 6 to 14 pounds in intervals of 1 pound. 6 has 3 dots. 8 has 5 dots. 9 has 1 dot. 10 has 7 dots. 12 has 4 dots. 13 has 2 dots. 14 has 1 dot. A baker purchases all of the pumpkins to make pies. If she uses a $100 bill to pay for the pumpkins, how much change will she receive? Enter your answer in the box. $

Answers

Answer:

The answer is 32.5

Step-by-step explanation:

First start with (6x3) + ( 8 x 5 ) + ( 9 x 1 ) + ( 10 x 7 ) + ( 12 x 4 ) + ( 13 x 2 ) + ( 14 x 1 ). This equals 225 pounds for all of the pumpkins. The baker buys all of them so multiply 225 by 0.30 since each pound costs 0.30. 225 x 0.30 = 67.5 and the baker pays a 100 dollars so 100 - 67.5 = 32.5. The answer is 32.5.

Answers

The answer is c

Took the test

in the figure, c // d. What are the measures of <1 and <2? Enter your answers in the boxes. Just write the numbers. (not the degree symbols)

Answers

Answer:  <1 = 105° and <2 = 75°

Step-by-step explanation:

The information we have is the 75 degree angle already provided. Using our knowledge on transverses we know a 180 degree angle is a straight line (we happen to have two of these (c and d)). Using the corresponding angle theorem we know angle 2 is equivalent to 75 degrees. Supplementary angles refer to angles that add up to 180 degrees. Angle 1 and 2 are supplementary so from there we solve.

180 - 75 = 105

<1 = 105 degrees

[tex]x=4-\sqrt{2}[/tex] or [tex]x=4+\sqrt{2}[/tex]

Step-by-step explanation:

Plug in given values of a, b, and c into the quadratic formula and solve for x:

[tex]x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]

[tex]x=\frac{-8±\sqrt{8^{2}-4(-1)(-14) } }{2(-1)}[/tex]

[tex]x=\frac{-8±\sqrt{64-56 } }{-2}[/tex]

[tex]x=\frac{-8±\sqrt{8} }{-2}[/tex]

[tex]x=\frac{-8±2\sqrt{2} }{-2}[/tex]

[tex]x=4±-\sqrt{2}[/tex]

Therefore, the roots are [tex]x=4-\sqrt{2}[/tex] or [tex]x=4+\sqrt{2}[/tex]
