Solving Quadratic Equations-factoring
How do find what b could be? My book says to factor completely.
3b²+15b+12=0

Answers

Answer:

b  =  −1

b  =  −4

Step-by-step explanation:

Common Factor

Divide both sides of the equation by the same term

Use the quadratic formula

Answer:

-1 or -4

Step-by-step explanation:

first all you have to do is to multiply 12 by 3b² to give you 36b² and then find a number(x) multiplied by another number(y) to give you 36b² and those two numbers must sum up to give you 15b

doing this, we would have our two numbers to be

12b and 3b

replace these two numbers with 15b in the equation

3b² + 12b + 3b + 12=0

(3b²+12b) + (3b+12)=0

3b(b+4)+3(b+4)=0

note: the numbers in the brackets must be the same

(3b+3)(b+4)=0

therefore, 3b + 3= 0 or b + 4= 0

3b+3= 0

3b=-3

b=-3/3

b=-1

or

b+4=0

b=-4

Step-by-step explanation:

Select the equations corresponding to d, the distance between points (2, -6) and (2, 5).

a) d = |-6| – |5|
b) d = |2| – |2|
c) d = |5| – |-6|
d) d = |5| + |-6|
e) d = |2| + |2|
f) d = |-6| + |5|

Answers

The distance between points  (2, -6) and (2, 5) is d = |-6| + |5|.

In the first step, we plot the two points. Then, connect the two points. Count the distance between Quadrant I and Quadrant IV.

Quadrant I contains 5 units and quadrant IV contains 6 units. We know that the vertical line denotes the y-value. Therefore, we take the Quadrant IV value as -6.

Since, we use the determinant sign the result will be d = |-6| + |5|.

To find the distance between two points:

What is the volume of the triangular prism below? V = ft 3

Answers

Answer:

Step-by-step explanation:

Volume =base area* hight

The base is a right triangle so area is (18*2)/2=36/2=18

Vol =18*3 =54 ft^2

volume= 36*3=108ft^2

What is the volume of the figure below if a = 9 units and b = 7 units?

Answers

The answer is:

The reason is:

bottom one is a square prism. the volume formula is l x w x h. 9 x 9 x 9

square prism : 729

then the top one is a triangular prism. which is 1/2b x a x a
so 3.5 x 9 x 9

triangular prism: 283.5

The graph is positive this time, so right away you can eliminate A and B.

If y=2x, the graph would be much steeper so the answer is C.) you can also check by graphing it in desmos.

Answer: C: 1/2

Step-by-step explanation:

Rise over run tells us that this graph is going up 1 and right 2. Since it’s going up and right it’s going to be positive and since we do rise over run on our slope fraction, that leaves us with C, 1/2.
