I need help it’s hard

Step-by-step explanation:

[tex] \tt{2 {x}^{2} + 5x - 3 = 0}[/tex]

⇢ [tex] \sf{2 {x}^{2} + 5x + ( - 3) = 0}[/tex]

Here , a = 2 , b = 5 & c = -3 {a is the coefficient of x² , b is the coefficient of x and c is the constant term }

Now ,

[tex] \tt{x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} }[/tex]

⇢ [tex] \tt{x = \frac{ - 5± \sqrt{ {5}^{2} - 4 \times 2 \times ( - 3) } }{2 \times 2} }[/tex]

⇢ [tex] \sf{ x= \frac{ - 5±7}{4} }[/tex]

Taking positive ( + ) sign :

⇝[tex] \tt{x = \frac{ - 5 + 7}{4} = \frac{1}{2}} [/tex]

Taking negative ( - ) sign :

⇝[tex] \tt{x = \frac{ - 5 - 7}{4} = - 3}[/tex]

[tex] \purple{ \boxed{ \boxed{ \tt{⤑ \: Our \: final \: answer : \boxed{ \underline{ \tt{x = \frac{1}{2} , \: - 3}}}}}}}[/tex]

Answer:

hope it is helpful

Step-by-step explanation:

10 is the increase in number

orignal vale is 20

so

increase %=increase in orignal value/orignal value ×100

=10/20×100=50%

Explanation:

The order of the letters is very important. This is because the order tells us how the angles pair up and that leads to telling us how the sides correspond to one another.

Note with ABC and FGH, the first and last letters are AC and FH respectively. These sides correspond. We're told that FH is 1/3 as long as AC when your teacher wrote FH = (1/3)*AC; we can solve for AC to get AC = 3*FH.

Going back to ABC and FGH, we see that the first two letters of each are AB and FG. This is another pair of corresponding sides. We're told that 3*FG = AB. So AB is three times longer than FG.

So far we can see that

The missing information we need is that BC = 3*GH. If we know this, then we can use the SSS similarity theorem to prove the triangles are similar. Note how BC are the two last letters of ABC while GH are the last two letters of FGH.

Starting with BC = 3*GH, we can divide both sides by GH and we get BC/GH = 3.

Answer:

[tex]\$3463.70[/tex]

Step-by-step explanation:

Start by finding the total surface area of one block. The surface area of this half-cylinder is:

[tex]2\cdot\frac{1}{2}r^2\pi+\frac{1}{2}\cdot2r\pi\cdot h[/tex]

Since both radius and height are given, we can solve the equation:

[tex](1.5)^2\cdot \pi +1.5 \cdot \pi \cdot 4 \approx \fbox{$25.9\:\mathrm{cm^2}$}[/tex].

Since the company is painting 257 of these, the total surface area of all the blocks will be:

[tex]({(1.5)^2\cdot \pi + 1.5 \cdot \pi \cdot 4)\cdot 257\approx \fbox{$6660\:\mathrm{cm^2}$}[/tex].

Each square centimeter costs $0.52, so the total cost the company will have to pay is:

[tex]({(1.5)^2\cdot \pi + 1.5 \cdot \pi \cdot 4)\cdot 257\cdot 0.52\approx \fbox{$\$3463.70$}[/tex].

Answer:

[tex]\displaystyle 385[/tex]

Step-by-step explanation:

The rate of change [slope] of the graph is 35, and for every two blocks you horisontally move represents seventy blocks vertical-wise, therefore an ELEVENTH block would require you to split 70 in half, giving you 35, then add this to 350 to get 385.

I am joyous to assist you at any time.

Answer:

The answer is Option B.) 385

Step-by-step explanation:

The pace of progress of the chart is 35, and for each two squares you horizontally move addresses seventy squares vertical-wise, thusly an 11 square would expect you to part 70 fifty-fifty, giving you 35, then, at that point, add this to 350 to get 385 as a result.

Answer:

[tex]187.74\:\mathrm{cm}[/tex]

Step-by-step explanation:

The area of a rectangle is given by [tex]l\cdot w[/tex]. Therefore, we can set up the following inequality:

[tex]l\cdot 16 \leq 3,003.84[/tex].

Solving this inequality, we have:

[tex]l \leq 187.74[/tex].

Therefore, the largest length Carmen's painting can be is [tex]\fbox{$187.74\:\mathrm{cm}$}[/tex].

Answer: 8 + 3/4W

Step-by-step explanation:

From the question, we are informed that Leah is training for a bike race she start by biking 8 miles during every training session and that each week she plans to increase the distance of her training session by 3/4 mile W the number of weeks.

The expression to show the distance Leah bikes in a training session after W weeks will be:

= 8 + 3/4W

For example, after 4 weeks, the distance biked will be:

= 8 + 3/4W

= 8 + (3/4 × 4)

= 8 + 3

= 11 miles

Answer: 2592

Step-by-step explanation:

Answer:

2592

Step-by-step explanation:

Im going to separate this to a square and a rectangle

36*36=1296

72*18= 1296

so 1296+1296=2592

thus the answer is 2592

good luck

Answer:

the first one, 5(x-4) + 29

Step-by-step explanation:

Answer:

x = -3

Step-by-step explanation:

55 + 54 = 109

109 + 74 = 183

Triangles = 180 degrees

So, 74 - 3 = 71

And 55+54+71 = 180

Answer:

The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Step-by-step explanation:

To find: What is the constant term in the polynomial expression, and what does it represent?

The given expression is [tex]-8x^2 + 54x + 140[/tex].

To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.

=[tex]-8(0)^2 + 54(0) + 140[/tex]

=[tex]140[/tex]

The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.

Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Answer:

All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
