Answer:
callens expression makes sense because they are showing that the five is negative and it is also being multiplied to the set of parenthesis.
demetrius's expression is a simplified version of callens. Using the parenthesis around the -5 shows that not only is that number negative, but it will also be multiplied to the -4 in the parenthesis.

Consider the quadratic equation 3x^2-6=2x. (a) What is the value of the discriminant? (b) What does the discriminant of the quadractic equation tell about the solutions to 3x^2-6=2x?
Answer:
(a) discriminant is positive, 76
(b) the above tells you there are two real roots
Step-by-step explanation:
the discriminant is 'b² - 4ac'
3x² - 2x - 6 = 0 ∴ a = 3, b = -2, c = -6
(-2)² - 4(3)(-6) = 4 + 72
(a) The discriminant of the quadratic equation is positive, 76.
(b) The quadratic equation tells you there are two real roots.
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
The discriminant of a polynomial in mathematics is a quantity that depends on the coefficients and enables inference of some root features without computing them.
Given that the quadratic equation 3x²-6=2x.
The discriminant Of the quadratic equation is calculated by the formula below:-
D = b² - 4ac
3x² - 2x - 6 = 0 ∴
a = 3, b = -2, c = -6
Put the value of the coefficient to get the value of the discriminant.
D = (-2)² - 4(3)(-6) = 4 + 72 = 76
Therefore, the discriminant of the quadratic equation is positive, 76, and the quadratic equation tells you there are two real roots

Cost of shopping trip: $25.00
Find tax amount at 5%
$30.00
$26.25
$1.25
$5.00
Answer:
$1.25
Step-by-step explanation:
Given: the cost of the shopping trip is $25.00
They want us to find the tax amount at 5%.
Saying that we need to find the 5% of the $25.00.
Convert 5% to 0.05, then take it times 25.
$25 x 0.05 = $1.25
That should give you the 5% of the $25.
If you add $25.00 and the $1.25 together, it should give you $26.25, included with the tax.
Answer:
26.25
Step-by-step explanation:
first we have to add 25.00 plus 5%

This season, the probability that the Yankees will win a game is 0.54 and the probability that the Yankees will score 5 or more runs in a game is 0.6. The probability that the Yankees win and score 5 or more runs is 0.46. What is the probability that the Yankees would score 5 or more runs when they lose the game? Round your answer to the nearest thousandth.
Answer:
O.304
Step-by-step explanation:
0.14 / 0.46
The probability that the Yankees would score 5 or more runs when they lose the game will be 0.140
What is probability?Probability is synonymous with possibility. It is concerned with the occurrence of a random event. Probability can only have a value between 0 and 1.
The probability that the Yankees will win a game is, 0.54
The probability that the Yankees win and score 5 or more runs is 0.46
(P>5)=0.6
The probability that the Yankees would score 5 or more runs when they lose the game is found as;
P(fail and ,>5)=P(score>5)-P(win and score>5)
P(fail and ,>5)=0.6-0.46
P(fail and ,>5)=0.140
Hence,the probability that the Yankees would score 5 or more runs when they lose the game will be 0.140

Pleaaasseee help!!! BRAINLIEST FOR CORRECT ANSWER!! What is the transformation rule for a translation 3 units right?
Answer:
Rule: replace x by x - a where a is the number of units that you want to move right. a must be greater than 0. x - - a would move left.
Step-by-step explanation:
You want f(x) to move 3 units to the right.
That would mean that x would be replaced by x - 3. Just to be sure let's try it.
Suppose you have f(x) = x^2 + 6x + 5 It is graphed as the red lineNow suppose you want to move 3 units right. It would replaced like f(x - 3) = (x - 3)^2 + 6(x - 3) + 5 which is the blue lineNotice nothing else is changed. The blue line looks exactly like the red line except that it is shifted 3 units to the right.A wheelbarrow is used to carry wet concrete. The dimensions pf the tray

Answer:
volume = 415800
Surface Area inside = 26370
Step-by-step explanation:
slowly added up all sides for surface area.
volume is area of trapezoid side (b1 + b2 divided by 2 multiply by height) x bottom length (70)
trapezoid Area = 106 + 34 +40 Divided by 2 then multiply by 66
The volume of the wheelbarrow is 415800 cubic centimeter.
What is Area?Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is a wheelbarrow that is used to carry wet concrete. The dimensions tray are provided in the image.
We can write the volume of the wheelbarrow as -
V = {(1/2 x 34 x 66) + (66 x 40) + (1/2 x 66 x 66)} x 70
V = {1122 + 2640 + 2178} x 70
V= 415800 cubic centimeter.
Therefore, the volume of the wheelbarrow is 415800 cubic centimeter.
