HELP I NEED THIS REALLY FAST WILL GIVE BRANILIEST!!!

Hi! I hope you are enjoying your day!

Let's evaluate this expression for x.

We are given that

[tex]\bold{x=10}[/tex]

All we have to do in order to solve this expression is plug in the value of x.

[tex]\bold{x^2-2(x+5)}\\[/tex]

[tex]\bold{x^2-2x-10}[/tex]

Now, plug in the value of x:

[tex]\bold{10^2-2(10)-10}[/tex]

10² is equal to 100:

[tex]\bold{100-20-10}[/tex]

[tex]\bold{100-30}[/tex]

And that is equal to

[tex]\boxed{\boxed{\bold{70}}}[/tex]

Hope everything is clear.

If you have any questions, please comment.

plug in the value of x (10) and solve

Answer:

gene would have 45

Step-by-step explanation:

if you take 55 and times that by 2 you get 110 then gene would need a toyal of 90 to complete the 200 so if you divide 90 by 2 you get 45

Answer:

C is correct

Step-by-step explanation:

You divide by 2 and that leaves x+55=100-55=45

You would finish with 45

Answer:

The probability of an event is a number from 0(impossible) to 100(certain).

Probabilities are wriiten as: fractions, decimals, and percentages.

Tracy's explanation would be the simplest because 1\6 is half of one third she eliminated the need for an extra step if left the other way

Answer:

To determine if a number is prime or composite, follow these steps:

Step-by-step explanation:

1. Find all factors of the number.

2. If the number has only two factors, 1 and itself, then it is prime.

3. If the number has more than two factors, then it is composite.

So, if you can, you might want to use a calculator.

Explanation:

A negative trend is when one variable goes up and the other variable goes down (or vice versa).

As the temperature goes down, the heating bill is likely to go up. This is of course assuming the person(s) use the heat to stay warm rather than just solely rely on something like coats/blankets/etc.

As the temperature goes back up, there's little to no need for heating. So the heating bill will likely go down.

As the name implies, negative trend graphs have negative slopes for the regression lines.

Answer:

C

Answer:

Option D) (136-2a) + ( 3a + 39) = 180

Step-by-step explanation:

As per provided information .

XQR is a straight line So, sum of all angles formed on straight line is 180° .

This Means

∠XOM + ∠MOR = ∠XQR

On putting the given value we obtain

(136 - 2a) + (3a + 39) = 180

So, the required option is (D) (136 - 2a) + (3a + 39) = 180

You can solve it further to get the value of a .

Answer: 63 m

explanation: finding the area of the entire rectangle (so if the triangle wasn’t there) would be 13 x 6 which equals 78. Now we find the area of the triangle, so 6 x 5 = 30/2=15. Then you do 78-15, which equals 63. Hope this helped!

Hi! Hope you are having a nice day!

Slope Formula:

[tex]\sf{\displaystyle\frac{y2-y1}{x2-x1}[/tex]

[tex]\sf{\displaystyle\frac{1-(-6)}{-2-4}[/tex]

As we can see, Option B is the right option; all the other options are wrong.

Hope you could understand everything.

Answer:

23 inches

Step-by-step explanation:

Diameter: [tex]d=\frac{C}{\pi}[/tex]

[tex]d=\frac{C}{\pi} \\\\d=\frac{72}{3.14} \\\\d=22.929\\\\d=23[/tex]

Check your answer using the circumference of a circle: [tex]C=2*\pi*r[/tex]

Radius (r) = d/2. So 23/2 = 11.5

[tex]C=2*\pi*r\\\\C=2*3.14*11.5\\\\C=72.22\\\\C=72\ inches[/tex]

Hope this helps!

Answer: 15)a 45x-380

15)b no.

Step-by-step explanation: Because 380/45=8.4444 which that means it will take him 8 days to finish.

Answer: 6ft

the scale goes up by a factor of three by looking at the bottom numbers from the 3 to the 7, so you would apply that to the height too making it 3+3=6 ft

Answer:

Step-by-step explanation:

1. The length of the fish a fisherman catches, f, must be at least 8 inches for him to keep it.

8 inches <_f

2. The number of days, d, of sunshine is not 32.

i don't get this one sorry

3. The value, v, of the car is less than $8,400.

v<$8,400

4. The number of people, p, that a café can seat at once is no more than 53.

p<_53 people

5. The time, t, a customer has left on a parking meter is at least 13 minutes.

t<_13 minutes

6. The bill, b, was less than $56.

b<_$56

17, and 19 might be wrong. (just which way the arrow goes)

Answer:

6. integer, natural number

7.No

8. 6, 5.7

17. a=5

18.yes

19.yes

20.yes

explaination for 18-20: They all can be put into a fraction. For 18, after rooting both numbers, would be 1/3 (same with 20). For 19, it would be root 5 over 3.

Answer:

A and B

Step-by-step explanation:

they both equal 24.

Answer:

2a + 4 + 7b

Step-by-step explanation:

ohh so to do this umm if you want it to be easier you can put a different symbols under the ones with the same variable. like a dot under 4a and - 2a, a square under .....

but if you want to do it without that, all you have to do is add them like numbers

you can also move them closer to each other. for example:

4a - 2a + 8 - 4 + 7b

4 - 2 is 2 so you just have to write 2a

2a + 8 - 4 + 7b

simplify

2a + 4 + 7b

since there are no other numbers with the variable b the equation above is the answer

Answer:

C
