First, square each side of the equation. It will then say (3x+4)=16. Now subtract 4 from each side, and finally, divide each side by 3. The solution will then stare up at you: x=4 .

If a= 3 and b= -1, what is the value of ab-b’2?
ohaa [14]

a x b = -3. b x b = 1. Now whats -3 - 1? When a letter is right next to another letter without a space, that means it wants you to multiply the value of one letter by the other. for example, if x equals 2 and y equals 3, and they're right next to each other like this: xy that means you need to multiply x by y. X times Y = 2 times 3. 2x3=6. If you see a letter with a small number beside it, this means that it wants you to multiply the value of that letter by itself times the little number on the top. For example, if n equals 6, and the little number on the top right is 3, then that means you have to multiply 6 by 6 three times. 6 x 6 x 6 = 216.

Answer:

11 + 6\sqrt{2}

Step-by-step explanation:

(3 + \sqrt{2} )²

= (3 + \sqrt{2} )( 3 + \sqrt{2} )

Each term in the second factor is multiplied by each term in the first factor

= 3( 3 + \sqrt{2} ) + \sqrt{2} ( 3 + \sqrt{2} )

Distribute each parenthesis noting that \sqrt{2} × \sqrt{2} = 2

= 9 + 3\sqrt{2} + 3\sqrt{2} + 2 ← collect like terms

= 11 + 6\sqrt{2}

The HL theorem applies.

NM and OP are the hypotenuses, given to be congruent.
Angles at H are right angles.
Sides HM and HP are congruent because MHP is isosceles. You have the hypotenuse and one leg of a right triangle congruent, which is the premise for the HL theorem.

Answer:

(C)

Step-by-step explanation:

looking from the slope: f'(2) is negative

f(2)=0

the curve concave upward: f''(2) is positive

f'(2)<0

f(2)=0

0<f''(2)

f'(2)<0<f''(2)
