The other factor of the quadratic equation [tex]6x^{2} -7x+2[/tex] is 3x-2. Since it is a quadratic equation we can get the other factor by factorization.
Factorization of quadratic equation is a way of finding the roots of the equation.The simple method of factorizing is we first find the product of the coefficient of [tex]x^{2}[/tex] and the constant, then we have to get the product by rearranging the coefficient of x, if the constant has a positive sign then we try to get the product by sum and if the sign is negative then we try to get the product by subtraction. After rearrangement we divide the equation in two parts and take the common factors from each part.
One of the factors of the equation is 2x-1, we have to find the other factor.
[tex]6x^{2} -7x+2=0\\6x^{2} -3x-4x+2=0\\3x(2x-1)-2(2x-1)=0\\(2x-1)(3x-2)[/tex]
The other factor of the equation is 3x-2.

When Suzy walks past the coffee shop, she can pick up their free wi-fi signal, which extends 60 ft from the shop. She starts walking toward the coffee shop at a rate of 3 ft/sec from her office building 180 ft away. After how many seconds will she pick up the signal? If she keeps on walking past the coffee shop, after how many seconds will she lose the signal?
The number of seconds Suzy will pick up the signal if she starts walking toward the coffee shop at a rate of 3 ft/sec from her office building 180 ft away is 40 seconds
DistanceSignal distance = 60 ftSuzy's speed = 3 ft/secDistance between her office building and the coffee shop = 180 ftAfter how many seconds will she pick up the signal between her office building and the coffee shop = (Distance between her office building and the coffee shop - Signal distance) / Suzy's speed
= (180 ft - 60 ft) / 3 ft/sec
= 120 ft / 3 ft/sec
= 40 seconds
After how many seconds will she lose the signal = Signal distance / Suzy's speed
= 60 ft / 3 ft/sec
= 20 seconds
Therefore, If she keeps on walking past the coffee shop, she will lose the signal after 20 seconds.

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 55 pounds each, and the small boxes weigh 25 pounds each. There are 125 boxes in all. If the truck is carrying a total of 4775 pounds in boxes, how many of each type of box is it carrying?
There are 70 small boxes and 55 big boxes.
How to calculate the equation?Let x = small box
Let y = large box
The equation will be:
x + y = 125 ....i
25x + 55y = 4775 ..... ii
From equation i, y = 125 - x.
25x + 55y = 4775
25x + 55(125 - x) = 4775
25x + 6875 - 55x = 4775
Collect like terms
25x - 55x = 4775 - 6875
30x = 2100
x = 2100/30
x = 70
Since x + y = 125
y = 125 - 70 = 55
Therefore, there are 70 small boxes and 55 big boxes.

rs= 4x-9, st= 19, rt=8x-14
The value of x is 6
How to determine the valueFrom the information given, we have that;
Line RS = 4x - 9Line ST = 19Line RT = 8x - 14It is important to note that line RT is a line with segments RS and ST and S and the line between R and T
This can be expressed as;
RS + ST = RT
substitute the values into the equation, we have;
4x - 9 + 19 = 8x - 14
collect like terms
4x - 8x = -14 + 9 - 19
subtract like terms
-4x = -24
make 'x' the subject of formula
-4x/-4 = -24/-4
x = 6

Expand $(2t - 7)^2.$
Answer:
4t^2 - 28t + 49
Step-by-step explanation:
(2t - 7)^2
Use FOIL.
(2t - 7)^2 =
= (2t - 7)(2t - 7)
= 4t^2 - 14t - 14t + 49
Combine like terms.
= 4t^2 - 28t + 49
(2t - 7)² on expansion results in 4t² - 28t + 49.
What are Algebraic Identities?The algebraic equations which can be used for all variables in the equation is called Algebraic identities. These identities used in factorization of polynomial expressions as well as in the computation of algebraic expressions.
Some of the standard algebraic identities are:
(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
a² - b² = (a + b) (a - b)
Here we have the expression (2t - 7)².
Using the second identity (a - b)² = a² - 2ab + b², we can write,
(2t - 7)² = (2t)² - (2 × 2t × 7) + 7²
= 4t² - 28t + 49
Hence the expression (2t - 7)² is expanded to 4t² - 28t + 49 using the algebraic identity (a - b)² = a² - 2ab + b².

Step-by-step explanation:
u-v+w

We want to perform a sum of vectors and draw the resultant vector. The resultant vector will be <4, 0> and its graph can be seen at the end.
If we see the image, we can write the vectors as:
w = <3, 3>u = <-3, -4>v = <-4, -1>Now we want to sum:
u - v + w
Remember that in the sum of the vectors we just add (subtract) the correspondent components, then we will have:
u - v + w = <-3, -4> - <-4, -1> + <3, 3> = <-3 + 4 + 3, -4 + 1 + 3> = <4, 0>

Identify the property illustrated. (Commutative, Associative, Identity, Property of Zero, Property of -1)
1. -1 • (-6) =6
2. 0 • (-76.3) =0
3. (3x) y = 3 (xy)
4. 0.3 • (-3) = -3 • 0.3
-1 × (-6) = 6 ( because of multiplicative property of -1)
0 ×(-76.3) = 0 (zero property of multiplication)
(3x)y = 3(xy) (commuative property)
0.3 × (-3) = -3 × 0.3 ( commutative property)
As we know that,
The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
Identity property states that a number, known as the identity, can be added to, subtracted from, multiplied by, or divided into a number without changing the number.
Zero property of multiplication is defined as “when we multiply any number by zero, the resulting product is always a zero”.
Multiplicative property of -1 atates that any number multiplied by -1 gives the same but with its opposite sign.
From the given example we can say that
-1 × (-6) = 6 ( because of multiplicative property of -1)
0 ×(-76.3) = 0 (zero property of multiplication)
(3x)y = 3(xy) (commuative property)
0.3 × (-3) = -3 × 0.3 ( commutative property)
