General Idea:

The quadratic function of the form ax^2+bx+c=0.

Applying the concept:

Simplifying the equation in option A, we get...

A) \; 8 - 5x = 4(3x - 1) \\Distributing \; 4 \; in \; right \; side \; of \; the \; equation. \\ \\ 8 - 5x = 12x - 4\\ The \; equation \; is \; a \; linear \; equation \; with \; variable \; on \; both \; sides.

Simplifying the equation in option B, we get...

B) \; \; (4a + 2)(2a - 1) + 1 = 0\\ Multiplying \; First \; \; Outer \; \;  Inner \; \;  Last \;  terms\; in\;  the \; left \; side.\\ \\ 4a \cdot 2a + 4a \cdot -1 + 2 \cdot 2a + 2 \cdot -1 + 1 = 0\\ \\ 8a^2-4a+4a-2+1=0\\ Combining \; like \; terms \; \\ \\ 8a^2 - 1 = 0\\ Above \; is \; a \;  Quadratic \; Equation!

Simplifying the equation in Option C, we get...

C)\; \; 2y + 2(3y - 5) = 0\\ Distributing \; 2 \; in \; left \; side\\ \\ 2y+6y-10=0\\ Combining \; like \; terms\\ \\ 8y - 10 = 0\\ Above \; Equation \; is \; linear \; equation

Simplifying the equation in Option D, we get

D) \;2b(b - 7) + b = 0\\ Distributing \; 2b\; in \;the \;left\; side \;of \;the\;equation\\ \\ 2b \cdot b - 2b \cdot 7+b=0\\ Simplify \; in \; the \; left \; side \; of \; the \; equation\\ \\ 2b^2-14b+b=0\\ Combine \; like \; terms\\ \\ 2b^2-13b=0\\ Above \; equation \;is \;a \; Quadratic\;Equation!

<u>Conclusion:</u>

Option B) & Option D) are quadratic equation!

Thepotemich [5.8K]

Answer:

Step-by-step explanation:

s + r = 181

r = 119 + s

s + 119 + s = 181

2s + 119 = 181

2s = 181 - 119

2s = 62

s = 62/2

s = 31 <=== there are 31 senators

r = 119 + s

r = 119 + 31

r = 150 <=== there are 150 representatives

yan [13]

Answer:

1. 425,328 -> 425,330

2. 105,025 -> 105,030

3. 45,527 -> 45,530

4. 35,478 -> 35,480

5. 212,369 -> 212,370

Step-by-step explanation:

000,0<u>0</u>0 the underlined number is the tens place. In order for the tens place to round up the ones place must be 5 or above. If the ones place is lower than 5 you round down to the nearest tens.

In Example:

333,389 you would round up to 333,390 because of the 9 in the ones place.

Now, 333,333 you would round down to 333,330 because of the 3 in the ones place

Answer:

b=5V2

Step-by-step explanation:

Area =31 1/4 = b*12.5 sin45/2=b*12.5*V2/2* 1/2=12.5V2/4 *b

(31*4+1)/4=125/4

so 125/4= 12.5V2*b/4

12.5V2*b=125

b=125/12.5V2=10/V2=10V2/2=5V2
