3/5= .6
23 + 0.6= 23.6
23.6- 21.4= 2.2 seconds faster

I need help I don’t understand

Answer:

x=50

Step-by-step explanation:

A= 30+2x

B= x

Supplementary angles are angles that always add up to 180 degrees.

therefore, A + B=180 degrees

30 + 2x + x = 180: Now we solve

<em>30 + 3x =180 </em>

<em>subtract 30 from both sides</em>

3x=150

<em>divide by 3</em>

3x/3 = 150/3

x= 50

Which expression correctly simplifies (312415)56?

Andreyy89

Answer:

$\sf C)\quad \large\text{$\dfrac{3^{\frac{5}{12}}}{4^{\frac{1}{6}}}$}$

Step-by-step explanation:

Given expression:

$\large\text{$\left(\dfrac{3^{\frac{1}{2}}}{4^{\frac{1}{5}}}\right)^\frac{5}{6}$}$

$\textsf{Apply exponent rule} \quad \left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}:$

$\large\text{$\implies \dfrac{\left(3^{\frac{1}{2}}\right)^\frac{5}{6}}{\left(4^{\frac{1}{5}}\right)^\frac{5}{6}}$}$

$\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:$

$\large\text{$\implies \dfrac{3^{(\frac{1}{2}\times \frac{5}{6})}}{4^{(\frac{1}{5}\times \frac{5}{6})}}$}$

Simplify:

$\large\text{$\implies \dfrac{3^{\frac{5}{12}}}{4^{\frac{1}{6}}}$}$

Factor this expression completely. 18x^2 - 32

nata0808 [166]

Answer:

2(3x - 4)(3x + 4)

Step-by-step explanation:

Factorizing the below expression requires factoring common term.

$18 {x}^{2} - 32$

Obviously 2 is common to both 18 and 32. Thus, the answer is:

$= 2(9 {x}^{2} - 16)$

=2(3x - 4)(3x + 4)
