Respuesta:
(segundo + 3) (segundo + 2) = 0
Explicación paso a paso:
Dada la expresión cuadrática b² + 5b + 6, debemos factorizarla;
b² + 5b + 6 = 0
b² + 2b + 3b + 6 = 0
b (segundo + 2) +3 (segundo + 2) = 0
(segundo + 3) (segundo + 2) = 0
Por tanto, el factor requerido es (b + 3) (b + 2) = 0

Which matrix is matrix B?
Answer:
Option B
Step-by-step explanation:
Looking at the options, option B is correct because when multiplying it by matrix A, it yields the matrix AB as follows;
First row of A multiplied by first column of matrix in option D;
(1 × -1) + (0 × 0) + (0 × 0) = -1 which corresponds to the first number on the first row of Matrix AB
Since majority of matrix AB are zero, I will just prove the ones that are not zero.
Thus;
Second row of matrix A is multiplied by second column of matrix in option D;
(0 × 0) + (-1 × -1) + (0 × 0) = 1 which is same as 2nd number on second row in matrix AB
Lastly, third row of matrix A is multiplied by third column of matrix in option D;
(0 × 0) + (0 × 0) + (1 × -1) = -1 which is same as third number in third row in matrix AB
Answer:
Option B

The lengths of three sides of a rectangular rug are 25 inches, 50 inches, and 25 inches. What is the
length of the fourth side of the rug?
Answer:
50
Step-by-step explanation:
a rectangle has 2 of the same side lengths and another 2 of the same side lengths. We know that there is a 25 and 25, so there must be another 50 to that 50.

Caros makes wooden boxes without tops to use as flower planters. Each wooden box has a width of 14 inches and a height of 24 inches. The length of the box (x) varies depending on the type of flowers Carlos will plant. Which equation can be used to find the surface area (y ), in square inches, of a wooden box that has a length of x inches? Use the distributive property to help you solve.
Answer:
y = 2(31x + 336)
Step-by-step explanation:
The surface area of an open rectangular box of sides, l, w and h is
A = 2lh + 2wh + lw where l = length = x, w = width = 14 in and h = height = 24 in.
Since A = y, we have
y = 2lh + 2wh + lw
y = 2x(24) + 2(24)(14) + x(14)
y = 48x + 672 + 14x
y = 62x + 672
y = 2(31x + 336)

What is the slope-intercept form of the equation of a line that passes through (1,-6) with a slope of 5?
Answer:
y - y1 = m(x - x1)
y + 6 = 5 (x - 1)
y + 6 = 5x - 5
y = 5x - 5 - 6
y = 5x -11
y = mx + b
Slope intercept b = -11

A rectangle has an area of of 40 square inches, and one of its dimensions is 8, what is the missing dimension?
Answer:
5
Step-by-step explanation:
To get the area of a rectangle, you just multiply the width * Length. Since you already have one of the dimensions, then just do the oppositie of multiplication by dividing. So you would do 40/8 = 5.
Answer:
5 in
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is A = L*W.
Here, A = 40 in^2 = (8 in)x, so that
x = (40 in^2) / (8 in) = 5 in

Condense the following logarithm: 5log_4(a) - 6log_4(b)
Hi there! We are given the expression:
[tex] \large \boxed{5 log_{4}(a) - 6 log_{4}(b) }[/tex]
To condense or simplify the following logarithm. You have to remember these properties:
Properties - Logarithm
[tex] \large{ log_{b}(a)^{n} = n log_{b}(a) } \\ \large{ log_{b}(a) - log_{b}(c) = log_{b}( \frac{a}{c} ) }[/tex]
These two properties are what we need for our problem. Therefore,
[tex] \large{ log_{4}(a)^{5} - log_{4}(b)^{6} }[/tex]
We use the log_b(a)^n = nlog_b(a) property to convert in the form above. Next, we use the second property.
[tex] \large{ log_{4}( \frac{ {a}^{5} }{ {b}^{6} } ) }[/tex]
Answer
log base 4 of (a^5/b^6) is our simplifed form.Any questions can be asked through comment as I may reply soon. Thanks for using Brainly! Have a good day and happy learning! :)

A bag contains five red marbles and three green marbles. What is the probability of selecting one green marble from the bag?
(Hint: the answer is a fraction...)
Answer:
[tex]\boxed {\boxed {\sf P(green )=\frac{3 }{8}}}[/tex]
Step-by-step explanation:
Probability tells us how likely something is to happen. It's found by dividing the number of favorable outcomes by the total outcomes.
[tex]P=\frac{number \ of \ favorable \ outcomes}{total \ outcomes}[/tex]
Since we are trying to find the probability of selecting a green marble, that is the favorable outcome. There are 3 green marbles, so there are 3 favorable outcomes.
There are 5 red marbles in addition to the 3 green marbles. This means there are 8 total outcomes (5+3=8).
favorable outcomes = 3total outcomes =8[tex]P(green )=\frac{3 }{8}[/tex]
This fraction cannot be simplified further, so it is the answer.
The probability of selecting a green marble is 3/8

Answer:
a = 3b = -3Step-by-step explanation:
The remainder from division by (2x-3) is the same as the value of the function when that divisor is zero—at x = 3/2.
((2(3/2) +a)(3/2) +b)(3/2) -2 = 7
((3 +a)(3/2) +b)(3/2) = 9 . . . . add 2
9/2 +3/2a + b = 6 . . . . . . . . multiply by 2/3
3/2a +b = 3/2 . . . . . . . . . . . subtract 9/2
3a +2b = 3 . . . . . . . . . . . . . multiply by 2 [eq1]
The remainder from division by (x+3) is the same as the value of the function for x = -3.
((2(-3) +a)(-3) +b)(-3) -2 = -20
(-6 +a)(-3) +b = 6 . . . . . . add 2 and divide by -3
18 -3a +b = 6 . . . . . . . . . eliminate parentheses
3a -b = 12 . . . . . . . . . . . subtract 18, multiply by -1 [eq2]
Subtracting the [eq2] from [eq1], we have ...
(3a +2b) -(3a -b) = (3) - (12)
3b = -9 . . . . . simplify
b = -3 . . . . . . divide by 3
From [eq2], ...
3a -(-3) = 12 . . . . substitute for b
3a = 9 . . . . . . . . subtract 3
a = 3 . . . . . . . . . divide by 3
The values of 'a' and 'b' are 3 and -3, respectively.
