Need helppp plzzzzzz

it's good to write it out

length = 5 + width

area = 150

width = x

length = 5 + x

area = length * width

so

(5 + x) (x) = 150

5x + x^2 = 150

x^2 + 5x - 150 = 0

following you have to guess what 2 numbers when multiplied male 150 and when added make 5

and they are 15 and 10

(x +15) (x-10)

x = -15

x = 10

so the dimensions are

length = 15

and

width = 10

Answer:cos( A + B ) = cosAcosB - sinAsinB ;

cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;

tan²(x) - sin²(x) = sin²(x)/cos²(x) - sin²(x)

… = sin²(x) (1/cos²(x) - 1)

… = sin²(x) (sec²(x) - 1)

… = sin²(x) tan²(x)

Answer:

12.5% or .125

Step-by-step explanation:

4 options for the spinner all with equal probability, chance of spinning any number is 1/4; 2 options for the coin of equal probability so any side has a probability of 1/2. 1/4*1/2=1/8 chance; this is equal to 12.5% or .125.

there are 8 possible outcomes; 4 with spinner, 2 with coin, 4*2=8.

Darnell spends 3.32 hours on his phone this week.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Darnell wants to limit his screen time,

last week he spent an average of 3[tex]\frac{1}{2}[/tex] hours on his phone each day.

That means, 3.5 hours on the phone.

This week,

he reduced his screen time by 5% to the nearest hour.

That means,

3.5 x 5/100

= 3.5 - 0.17

= 3.32 hours.

Therefore, he spent 3.32 hours this week.

Answer:

175

Step-by-step explanation:

All you have to do is multiply 35% with 500. You can use a calculaor to do this it is very easy.

Given:

The quadratic equation is:

[tex]x^2-32x+54=0[/tex]

It can be written as [tex]-p=202[/tex].

To find:

The value of p in the rewritten equation.

Solution:

We have,

[tex]x^2-32x+54=0[/tex]

Isolate the constant term.

We need to make 202 on the right side. So, add 256 on both sides.

[tex]x^2-32x+256=-54+256[/tex]

[tex]x^2-32x+256=202[/tex]

[tex]-(-x^2+32x-256)=202[/tex]

Let [tex]-x^2+32x-256=p[/tex], then

[tex]-p=202[/tex]

Therefore, the value of p is [tex]-x^2+32x-256[/tex].

The given equation can be written as:

[tex]54=-x^2+32x[/tex]

Adding 148 on both sides, we get

[tex]54+148=-x^2+32x+148[/tex]

[tex]202=-(x^2-32x-148)[/tex]

Let [tex]x^2-32x-148=p[/tex], then

[tex]202=-p[/tex]

Therefore, the another possible value of p is [tex]x^2-32x-148[/tex].

Answer:

P(x)= x ^4-3x^3+x^2-4    

Step-by-step explanation:

Given data

R(x) = 2x ^4-3x^3+2x-1

c(x)=x^4-x^2+2x+3

We know that

P(x)=R(x)-C(x)

Hence

P(x)= 2x ^4-3x^3+2x-1-(x^4-x^2+2x+3)

open bracket

P(x)= 2x ^4-3x^3+2x-1-x^4+x^2-2x-3

Collect like terms

P(x)= 2x ^4-x^4-3x^3+x^2-2x+2x-3-1    

P(x)= x ^4-3x^3+x^2-4

Answer:

Step-by-step explanation:

For number 1: They are alternate interior angles, so you can set them equal to each other and find the answer that way. The pic is a bit blurry, but I think it's 4x=136, which is simplified to x=34.

For number 2: These are supplementary angles, which means that they add up to 180. 180-125 is 55, which means that 3x+1=55. Simplifying that, x=18.

Number 3: Once again alternate interior angles, which means that 53=x-11. Simplify that and you get x=64

Number 4: These are same side interior angles, and they are supplementary/add up to 180. x+12+110=180. Solved: x=58

Number 5: Same side interior angles. I cant make out the exact numbers on the picture, but basically you add them together and set that equal to 180, then solve like i did above.

Number 6: Alternate interior, so just set them equal to eachother and solve.

Number 7: Same side interior, so add them and set the whole thing equal to 180 like in number 4. Answer: x=10

Number 8: Alternate interior, so just set them equal to eachother. Answer: x=20

Answer:

48 ounces

Step-by-step explanation:

Answer:

64 ounces.

Step-by-step explanation:

combined weigh = weight of cat 1 + weight of cat 2

combined weigh = 17 + 12 = 29 pounds

The difference in weight of the Dog's weigh by the combined cat's weigh is the subtraction between the two, so we have:

Difference in weigh = 33 - 29 = 4 pounds

We now have to convert it to ounces, since 1 pound contains 16 ounces we can multiply the value of the weigh in pounds by 16 to obtain the final value:

Difference in weigh = (4 pounds)* 16 = 64 ounces

e^0.6 to the nearest hundredth using the first five terms of the exponential series of eˣ is; e^(0.6) =  1 + 0.6 + 0.6²/2! + 0.6³/3! + 0.6⁴/4....

We want to use the first 5 terms of the exponential series of eˣ to approximate e^(0.6)

The type of exponential series we will utilize is called the Maclaurin Series for. Thus, for eˣ, we have;

eˣ = 1 + x + x²/2! + x³/3! + x⁴/4.....

Thus;

e^(0.6) =  1 + 0.6 + 0.6²/2! + 0.6³/3! + 0.6⁴/4....

e^(0.6) = 1 + 0.6 + 0.18 + 0.072 + 0.0324

e^(0.6) = 1.88 to the nearest hundredth
