Answer:
x = 1 , x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
2x² - 5x + 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 3 = 6 and sum = - 5
The factors are - 2 and - 3
Use these factors to split the x- term
2x² - 2x - 3x + 3 ( factor the first/second and third/fourth terms )
2x(x - 1) - 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x - 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

In the given figure, no pair of opposite sides are parallel.
There are no parallel side in the given figure.
Given is a figure we need to determine if there are any parallel side or not,
So, the parallel sides are defined as =
When two or more sides of a polygon are described as parallel, it means that they never cross over and are always equally spaced apart.
In other words, these sides would never intersect or cross each other if you extended them endlessly.
Shapes like squares, parallelograms, rectangles, and trapezoids are frequently linked to the idea of parallel sides.
The opposing sides of these polygons are parallel to one another. For instance, just one pair of opposite sides in a trapezoid is parallel but both sets of opposite sides are parallel in a rectangle.
So according to the definition of parallel lines there are no parallel sides in the figure.

Cereal is packaged in boxes weighing 24.3 ounces. What is the weight of a
case of 48 boxes of cereal?
Answers
Answer:
1166.4
Step-by-step explanation:
Assuming this is the whole question, you multiply the weight of a single box by the amount in a case to find the weight of a case, hence 24.3*48 =1166.4
1 box of cereal = 24.3
48 boxes of cereal = 24.3 × 48
48 boxes of cereal:-
=> 24.3 × 48
=> 1166.4
Therefore, 48 boxes of cereal weighs 1166.4

What is the value of x in the equation 5 − 3x = −7?

5 − 3x = −7

Given :
5 − 3x = −7⠀
To Find :
The required value of x .⠀
Solution :
[tex]\qquad \sf \: { \dashrightarrow 5 - 3x = - 7}[/tex]
⠀
Adding (–5) to both sides :
[tex]\qquad \sf \: { \dashrightarrow 5 + ( - 5) \: − 3x = −7 + ( - 5)}[/tex]
[tex]\qquad \sf \: { \dashrightarrow \: − 3x = - 12}[/tex]
⠀
Dividing both sides by 3 :
[tex]\qquad \sf \: { \dashrightarrow \dfrac{ - 3x}{3} = \dfrac{ - 12}{3} } [/tex]
[tex]\qquad \sf \: { \dashrightarrow − x = −4}[/tex]
⠀
Cancelling (–) from both sides we get :

Here n = 6 , then
sum = 180° × 4 = 720°
Sum the interior angles and equate to 720
140 + 150 + 90 + x + 130 + 90 = 720 , that is
x + 600 = 720 ( subtract 600 from both sides )
x = 120

Donna is collecting stamps. On the first day, she collects 5. On the second day, she collects 9. Each day, she collects 4 more stamps than the day before. How many total stamps will she have after 20 days?
Answers
Answer:
81 stamps
Step-by-step explanation:
Here we will use the AP formula
We know that
a_n = a + (n - 1)d
a = first term = 5
n = number of terms = 20
d = common difference = 9 - 5 = 4
On putting values
=> a_20 = 5 + (20 - 1)4
=> a_20 = 5 + (19)4
=> a_20 = 5 + 76
=> a_20 = 81
Therefore,
She will have 81 stamps after 20 days
[tex]\huge{\purple{\underline{\underline{\sf{\pink{ANSWER:-}}}}}}[/tex]
Here we have,
first term (a) = 5no. of terms (n) = 20 common difference (d) = 9 - 5 = 4[tex]\implies\tt{a_n = a + (n - 1) \times d} \\ \\ \implies\tt{a_20 = 5 + (20 - 1) \times 4} \\ \\ \implies\tt{a_20 = 5 + 19 \times 4} \\ \\ \implies\tt{a_20 = 5 + 76} \\ \\ \implies\tt{a_20 = 81}[/tex]
Hence, there will be 81 stamps after 20 days.solve the following eqation: -8.2 + t/-2 = 1.7
Answers
Answer:
t = -19.8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]-8.2 + \frac{t}{-2} = 1.7[/tex] [tex]-8.2 - \frac{1}{2}t = 1.7[/tex] [tex]-\frac{1}{2}t - 8.2 = 1.7[/tex]Step 2: Add 8.2 to both sides.
[tex]-\frac{1}{2}t - 8.2 + 8.2 = 1.7 + 8.2[/tex] [tex]-\frac{1}{2}t = 9.9[/tex]Step 3: Multiply both sides by -2.
[tex]-\frac{1}{2}t * (-2)= 9.9 * (-2)[/tex] [tex]t = -19.8[/tex]If a rotation takes triangle CAT to C'A'T', what is C'T'?

Answer:

Step-by-step explanation:
the A point is in line with 10 squared and its in line with the 17 squared
The measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.
What is a rotation transformation?A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The graph shows the triangle CAT.
If a rotation takes triangle CAT to C'A'T',
then from the definition of rotation transformation the size and shape of the figure stays exactly the same.
Thus the measure of C'T' is same as CT.
⇒ [tex]C'T' =\sqrt{17}[/tex]
Hence we can conclude that the measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.
