Hi there,

Remove parenthesis,
7 + 9 + (-4)

Then, use the addition and subtraction rules:
7 + 9 - 4

Hence, the answer is 12 (C)

Hope this helps :)

Because the two triangles are congruent you can set the two expressions equal to each other and solve from their.

step 1 ) 8Y = 6Y + 8

step 2 ) isolate the variable to one side 8Y-6Y= 8 => 2Y = 8

step 3 ) solve for Y 2Y/2 = 8/2

Solution Y=4

What number is represented by −3x²+√2x+1/2 when x=√2?

Mila [183]

Answer:

at x = $\sqrt{2}$ , $-3x^{2} + \sqrt{2}x + \frac{1}{2}$ = -3.5

Step-by-step explanation:

The given equation is $-3x^{2} + \sqrt{2}x + \frac{1}{2}$

Now, substitute the value of x = $\sqrt{2}$ in the above equation.

The given equation simplifies to,

$-3(\sqrt{2})^{2} + (\sqrt{2})(\sqrt{2}) + \frac{1}{2}$

now, $\sqrt{2} . \sqrt{2} = 2, \textrm{and} (\sqrt{2} )^{2} = 2$

So, the equation become

-3(2) + 2 + (1/2) = $-6 + 2 + \frac{1}{2} = -4 + \frac{1}{2} = \frac{-8 + 1}{2} = \frac{-7}{2}$

= -3.5

So, at x = $\sqrt{2}$ , $-3x^{2} + \sqrt{2}x + \frac{1}{2}$ = -3.5
