I WILL BE MARKING BRAINLIST!

The required solution of the given expression is a = 9 + b- c. Option A is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression
√a−b+c=3
Squaring both sides,
a - b + c = 9
Rearrange the equation in order of a,
a = 9 + b - c

Thus, the required solution of the given expression is a = 9 + b - c. Option A is correct.

Answer:

The length of the garden is 94 m.

Step-by-step explanation:

you do 5828 m. divided by 62m. and that is how you get your answer of 94 m.

Answer:

94

Step-by-step explanation:

Area of a rectangle = Length x Width

5828 = L x 62

Length = 5828/62

Length = 94

Answer:

x = 132°

Step-by-step explanation:

sum of total exterior angles = 360°

x + 147° + 81° = 360°

x + 228° = 360°

x = 360° - 228°

x = 132°

Step-by-step explanation:

Answer:

From narrowest to widest:

1) [tex]8\cdot x^{2} + 2\cdot x +5[/tex]

2) [tex]5\cdot x^{2}-1[/tex]

3) [tex]2\cdot x^{2}+4[/tex]

4) [tex]\frac{2}{5}\cdot x^{2}+3\cdot x -5[/tex]

Step-by-step explanation:

The "width" of the quadratic function is determined by the value of the coefficient associated by the monomial of highest grade, with respect to the primitive of the quadratic function, represented by [tex]y = x^{2}[/tex], whose ruling coefficient is 1. If the ruling coefficient of the quadratic function is greater than  one, then the curve becomes narrower at the same time that the coefficient increases. Otherwise, if the ruling coefficient of the quadratic function is greater than zero and less than 1, then the curve becomes wider at the same time that the coefficient approximates to zero.

Based on this considerations, we proceed to list the quadratic functions from the narrowest to widest:

1) [tex]8\cdot x^{2} + 2\cdot x +5[/tex]

2) [tex]5\cdot x^{2}-1[/tex]

3) [tex]2\cdot x^{2}+4[/tex]

4) [tex]\frac{2}{5}\cdot x^{2}+3\cdot x -5[/tex]

Lastly, we include a graphic with all polynomials (tagged as 1, 2, 3, 4) in comparison primitive function (tagged as 0).

x = -1

Step-by-step explanation:

4/12 can be simplified to 1/3

1         x+2

---  = --------------

3          2x+5

Using cross products

1 ( 2x+5) = 3 (x+2)

Distribute

2x+5 = 3x+6

Subtract 2x from each side

2x+5-2x = 3x+6-2x

5 = x+6

Subtract 6 from each side

5-6 = x+6-6

-1 =x

Answer:

Step-by-step explanation:

Key skills: Proportions, One variable equations, Multiplication, Distribution Property

1) The best approach to this problem is with cross multiplication.

Cross multiplication is where we multiply the numerator of one fraction with the denominator of the other fraction, and the denominator of one fraction with the numerator of the other fraction.

2) Here we would do: 4(2x+5) and 12(x+2)

3) Since this is a proportion --> 4(2x+5) = 12(x+2)

4) Now, we use distribution property to expand both.

4(2x+5) --> 8x+ 20                      12(x+2) --> 12x+24

5) With simplifying we can solve for x:

If you plug in x=-1 back into the equation: 4/12= 1/3

4/12 does equal 1/3 so x= -1 is the right answer.

Answer: 42650

Step-by-step explanation:

The tens place is behind the ones place.

The number in the tens place in 42653 is 5.

So to round to the nearest tens you have to change three to 0 because if the number in the ones place is 5 or more, then the number in the tens place would be 1 higher than it used to be while the number in the ones place turns to 0.

However if the number in the ones place is less than 5, then that's the only thing that changes, the ones place would change into a '0.'

Hope that helped!

42650 is the value of the 426563 when rounded to the nearest ten.

The value a digit in a number represents based on where it is in the number is known as place value.

Given, the number 42653 which is rounded to the nearest ten value needs to find. Since,

The one's place is in front of the tens place.  In the number 42653, the tens place value is 5. The number three must be changed to 0 in order to round to the next tens because, if the number in the one's place is 5 or greater, the number in the ten's place would be 1 higher than it was previously while the number in the one's place would become 0. The one's place would change to a "0" if the number in the one's place is less than 5, but that is all that changes.

Therefore, When rounded to the nearest ten, 42650 represents the value of 426563.

Answer:

70°

Step-by-step explanation:

All triangles' angles are added up to 180°

30 + 80 + x = 180

110 + x = 180

x = 180 - 110

x = 70

Answer:

[tex]x = 70[/tex]

Step-by-step explanation:

[tex]x = 180 - (30 + 80)[/tex]

[tex]x = 180 - 110[/tex]

[tex]x = 70[/tex]
