Express the sum of (square root) -64 and 3(square root) -4 as a monomial in terms of I.
Inga [223]
\bf \sqrt{-64}~+~3\sqrt{-4}\implies \sqrt{-1\cdot 2^6}~+~3\sqrt{-1\cdot 2^2}
\\\\\\
\sqrt{-1}\cdot \sqrt{2^6}~+~3\sqrt{-1}\cdot \sqrt{2^2}\implies i\cdot \sqrt{2^{3\cdot 2}}~+~3\cdot i\cdot 2
\\\\\\
i\cdot \sqrt{(2^3)^2}~~+~~6i\implies 2^3i~+~6i\implies 8i+6i\implies 14i

Two numbers, a and b, have a sum of 24. The
mina [271]

Answer:

a= -12 and b=36

Step-by-step explanation:

a+b=24 and 3a+b

a-3a+b=24

-2a+b-b=24

-2a/-2=24/-2

a= -12

then substitute the value of a in a+b=24 to get the value of b

so let see -12+b=24

b=24+12

b=36

we can check it by the equation -2a+b-b=24

-2(-12)+36-36=24

24=24 so as you have seen the answer is correct

thanks!!!

Apply THe ORder of operations to simplify the expression
Galina-37 [17]
First either add or subtract the number in the parenthesis (3^2-4) which equals to 5 

90/[10+5) add the number in the parenthesis again (always do the parenthesis first) [10+5]= 15.

lastly divide 90/15 which equals to 6
always remember (PEMDAS)

Solve the quadratic equation: 2x2 + 11x − 6 = 0
Ostrovityanka [42]

Answer:

see explanation

Step-by-step explanation:

To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term.

product = 2 × - 6 = - 12 and sum = + 11

The factors are + 12 and - 1

Use these factors to split the middle term

2x² + 12x - x - 6 = 0 ( factor the first/second and third/fourth terms )

2x(x + 6) - 1(x + 6) = 0 (factor out (x + 6) )

(x + 6)(2x - 1) = 0

equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

2x - 1 = 0 ⇒ x = \frac{1}{2}
