Step-by-step explanation:
Carlos and Clarita were asked to write y=2x2+4x-6 in factored form.
What do you think?
Answer:
2(x+3)(x-1)
Step-by-step explanation:
Because 2x^2+4x-6 can be divided by 2, you can divide them by two. This would make the equation 2(x^2+2x-3). To factor this, you have to find two equation that would make it true. The equation have to be _+_=2 and _x_=-3. The two blanks would be 3 and -1. 3+-1=2 and 3x-1=-3. This means that the equation is 2(x-1)(x+3).

Answer:
x > -2.5 (-2.5, infinity)
Step-by-step explanation:
Given the inequality expression
5.1(3 + 2.2x) > –14.25 – 6(1.7x + 4
Expand
15.3 + 11.22x > -14.25 - 10.2x - 24
15.3 + 11.22x > -38.25 - 10.2x
Collect the like erms
11.22x + 10.2x > -38.25 - 15.3
21.42x > -53.55
x > -53.55/21.42

A dartboard has 20 equally divided wedges and you are awarded the number of points in the section of your dark lands in if you are equally likely to land in anyways what is the probability you were score more than five points
Answer:
[tex]Pr =0.75[/tex]
Step-by-step explanation:
Given
See attachment for wedge
Required
[tex]P(x > 5)[/tex]
The sample space of the wedge is:
[tex]S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]
[tex]n(S) = 20[/tex]
The outcomes greater than 5 are:
[tex]x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]
[tex]n(x>5) =15[/tex]
So, the probability is:
[tex]Pr =\frac{(n(x>5)}{n(S)}[/tex]
This gives:
[tex]Pr =\frac{15}{20}[/tex]
[tex]Pr =0.75[/tex]

2 out of 50 are defective.
Divide 2 by 50: 2/50 = 0.04
Now multiply the total quantity by that:

Collete mapped her vegetable garden on the graph below. Each unit represents 1 foot. Collete plants an 8-foot row of lettuce in the garden. Which points could tell where the row of lettuce starts and ends?
Answer:
(-4,-1) and (-4,7)
Step-by-step explanation:
If Collete planted a row of lettuce, that means their coordinates must have the same vertical coordinate, or the same horizontal coordinate. Another important characteristic is that between those points, there must have 8 units of separation, because it's an 8-foot row.
The ratio of mass of kangaroo to the mass of a penguin is 7:2. The kangaroo weighs 56 kg. What is the mass of penguin?
Answer: 16
Step-by-step explanation:
I think my answer is correct because, if kangaroo is 56 kg and the ration kangaroo to penguin was 7:2 I think we just have to divide 7 by 56. And 56 divided by 7 equals=8. and Since the pengiuins ration is 2 we just have to multiply 8 and 2. And 8 times 2 equals 16.

Answer:
area = 118.04 units²
Step-by-step explanation:
area of circle = πr² = (3.14159)(8²) = 201.06 units²
area of triangle:
corner angle - 60°/2 = 30°
sin 30° = m/8, m = 4
height of triangle = 4 + 8 = 12
cos 30° = n/8, n = 6.93, n = 1/2 base
base of triangle = 13.86
area of triangle = 1/2bh = 1/2(13.86)(12) = 83.02 units²
area of shaded portion = 201.06 - 83.02 = 118.04 units²

Answer:
9) 1/48
11) 1/24
13) 5/16
14) 1/8
Step-by-step explanation:
9) P(A and 5) = 1/8 × 1/6
11) P(J and LT 3) = 1/8 x 2/6
13) P (consonant and odd) = 5/8 x 1/2
14) P ('M' or 'T' and GT 3) = [(1/8+1/8) × 1/2] = 2/8 x 1/2

Trapezoid ABCD has been translated down and to the right to form trapezoid RSTU. Given that AB ll DC, Which of the following statements is true concerning trapezoid RSTU?
The true statements concerning trapezoid RSTU are:
STUT
CABRS
DRS UT
Based on the given information that Trapezoid ABCD has been translated down and to the right to form trapezoid RSTU, we can determine the relationships between the corresponding sides and angles of the two trapezoids.
Given:
AB || DC
Based on the parallel lines, we can infer the following relationships:
Corresponding sides are parallel:
RS || UT (corresponds to AB || DC)
ST || RU (corresponds to BC || DA)
Corresponding angles are congruent:
∠R ≅ ∠A
∠S ≅ ∠B
∠T ≅ ∠C
∠U ≅ ∠D
From these relationships, we can determine the following statements that are true concerning trapezoid RSTU:
STUT (corresponds to ABCD): The bases of the trapezoids are parallel, so the order of the vertices remains the same.
CABRS (corresponds to DCBA): The corresponding angles in trapezoid RSTU and trapezoid ABCD are congruent.
DRS UT (corresponds to ABDC): The order of the vertices is reversed, but the parallel sides and corresponding angles remain the same.
Therefore, the true statements concerning trapezoid RSTU are:
STUT
CABRS
DRS UT

What is the area in square centimeters of the trapezoid below
Answer:
area = 1/2(a+b)h
a= 8.2 cm
b= 22.9 cm.
h= 9.8
therefore area = 77.91 sqcm
The area in square centimeters of the trapezoid below is 77.91 .
How to find the area of a trapezoid?The area of a trapezoid is the half of the product of sum of its parallel sides to the height of that trapezoid (the distance between those parallel sides).
Thus, if we have Length of its parallel sides = 'a' and 'b' units respectively
Perpendicular distance between its parallel sides = 'h' units,
Area = 1/2(a+b)h
a= 8.2 cm
b= 22.9 cm.
h= 9.8
Area = 1/2(8.2 + 22.9)9.8
therefore, area = 77.91 sqcm
