Help! Find all solutions to the equation (x - 1)^2 = -4.

Answer:

14.62

Step-by-step explanation:

23.4-8.78

so align it like if you were going to subtract it like this:

23.4

- 8.78

You have to add a zero behind the four just so it can be easier for you,

23.40

- 8.78

--------

Now subtract it

I will give you the answer so you know if you are correct or wrong

Answer: Bridge is 21 years old

Step-by-step explanation:

Ok so after reading the question I already know that B (Bridget), A (Angad) and P (Paul) is 49 in the sum of age. I also know that B=A+5 and P=A-4. After that I can assume B=P+5+4. So now after we gather everything, the age of all of them is the same if we delete 5, 4, 4 (From B=P+5+4 and P=A-4). 49-5-4-4=36. So now lets assume they are all 12 (36/3=12). B is 5 years older so lets add 5 to B. B=17, A=12 and P=8. 8+12+17= 37. We now know that but 37 is 12 under 49, so lets add the average 12/3=4 so we add 4 to all of them. B=21 A=16 P=12. 21+16+12=49. So Bridge is 21 years old, Angad is 16 years old and Paul is 12 years old

Answer:

X=2

Step-by-step explanation:

I'm sure it's the result.. Jdjdj

Answer:

Replacing x = 1 in the equation above, we have: (4x1) + 22 = 13

=> 5 +22 = 13 => 27 [tex]\neq[/tex] 13

So 27 is not equal to 13 => x=1 is not a solution to 4x+22 = 13.

You have to have a solution to factor out the x

Answer: 150

Step-by-step explanation:

Negatives cancel each other out so it’s a positive number and 30 times 5 is 150.

Answer:

24°

Step-by-step explanation:

Let's represent the unknown angle with x

So ;

66+x=90

x=90-66

x=24°

Therefore 24° is the missing angle.

Answer:

24°

Step-by-step explanation:

The missing angle is 90-66 = 24°.

5/8 is greater then 7/12.

Step-by-step explanation:

Find the least common denominator or LCM of the two denominators:

LCM of 8 and 12 is 24

For the 1st fraction, since 8 × 3 = 24,

5/8=5x3/8x3=15/24

Likewise, for the 2nd fraction, since 12 × 2 = 24,

7/12= 7x2/12x2=14/24

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

15/24>14/24 or 5/8>7/12

Answer:

$3.50

Answer:

Answer: B. x=7

Step-by-step explanation:

Similar Triangles

Assuming the up arrows indicate parallel lines, then triangles PQT and PRS are similar. See the image provided below.

Similar triangles have their side lengths proportional by a constant scale factor. They also have all of their internal angles congruent, or with the same measure.

This means that the marked angles are equal:

2x + 5 = x + 12

Subtracting x

x + 5 = 12

Subtracting 5:

x = 7

Answer: B. x=7

Answer:

B

Step-by-step explanation:

because 4(x+3)=6x+16 is true

4(-2+3)=6(-2)+16

4(1)= -12+16

4=4

Step-by-step explanation:

Answer:

The new pressure P₂  is 3.3 atm

Step-by-step explanation:

Pressure of gas = 2.7 atm

Volume = 3.6 L

Temperature = 324 K

Now we are given that  volume of the gas is kept constant.

Temperature is increased to 396 K

We need to find the pressure.

The formula used is: [tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

We have P₁ = 2.7

T₁ = 324 K

T₂ = 396 K

P₂ = ?

Putting values in the formula and finding P₂

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}\\\frac{2.7}{324}=\frac{P_2}{396}\\P_2=\frac{2.7}{324}\times 396\\P_2=0.0083 \times 396\\P_2=3.3[/tex]

So, the new pressure P₂  is 3.3 atm

¿Dónde está la leche?

Step-by-step explanation:

Answer:

A= 100+20h B=40h

Step-by-step explanation:

A=100+20h

B= 40h

Answer:

For company A:

100 + (20h)

OR

100 + (20 x h)

For company B:

40h

OR

40 x h

Step-by-step explanation:

For company A, you are multiplying 20 by h because you must pay $20 per hour. Then, you have to add 100 to that because there is a $100 dollar rental fee.

For company B, you are multiplying 40 by h because you must pay $40 per hour. There is no rental fee, so that means you don't have to add anything.

Hope this helps!
