whats 10 +78*5-9 divide by 6 nd i give yu yo answer nd ik the answer to the question i gave yu !

Step-by-step explanation:

Answer:

25[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying the radicals

[tex]\sqrt{98}[/tex] = [tex]\sqrt{49(2)}[/tex] = [tex]\sqrt{49}[/tex] × [tex]\sqrt{2}[/tex] = 7[tex]\sqrt{2}[/tex]

[tex]\sqrt{32}[/tex] = [tex]\sqrt{16(2)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex]

Thus

3[tex]\sqrt{98}[/tex] + [tex]\sqrt{32}[/tex]

= 3(7[tex]\sqrt{2}[/tex] ) + 4[tex]\sqrt{2}[/tex]

= 21[tex]\sqrt{2}[/tex] + 4[tex]\sqrt{2}[/tex]

= 25[tex]\sqrt{2}[/tex]

If 3x+4=-5, what does x equal to?​

Answers

First subtract 4 from both sides to isolate the 3x.

That leaves us with 3x = -9.

Since x is being multiplied by 3, to get x by itself,

we need to divide both sides of the equation by 3.

So our final answer is x = -3.

Answer:

x = -3

Step-by-step explanation:

3x + 4= -5

Subtract 4 from both sides.

3x = -9

Divide both sides by 3.

x = -3

3/4x + 2/5 = 4x - 1/4x

Answers

Answer: x=2/15

Ya I think so.

Answer:

4/45 = x

Step-by-step explanation:

Strongly suggest that you enclose the fractional coefficients inside parentheses to reduce possible ambiguity:

(3/4)x + 2/5 = 4x - (1/4)x

Consolidate the x terms on the right side and leave the 2/5 on the left:

2/5 = (4 - 1/4 + 3/4)x, or

2/5 = (4 1/2)x   or 2/5 = (9/2)x

Solving for x:  Multiply both sides by (2/9):

(2/9)(2/5) = (2/9)(9/2)x, or:

4/45 = x

Expand (-2x)^4

(-2)^4 x^4

-2^4= 16

=16x^4

Hope this helps

The simplification of the given equation [tex](-2x)^4[/tex] is [tex]16 * x^4[/tex].

Exponents are mathematical notation used to indicate repeated multiplication of a number or expression by itself.

They are written as superscript numbers or symbols placed to the right and slightly above the base number or expression.

To simplify (-2x)^4, you can apply the power rule for exponents.

(-2x)^4 can be expanded as follows:

(-2x)^4 = (-2)^4 * x^4

Now, evaluate the exponent of the base -2 and x:

(-2)^4 = 16

Thus, the simplified expression is: [tex](-2x)^4 = 16 * x^4[/tex]
