You didn't specify the topic so I will solve it in 3 topics
solving for a, you take roots of both sides and solve a=18,-18
using the quadratic formula, solve the equation for aa by finding aa, bb, and ccof the quadratic then applying the quadratic formula.

a=±√321a=±321

a≈17.91647286,−17.91647286

for factoring, Factor and set each factor equal to zero.

a=√321,−√321a=321,-⁢321

a≈17.91647286,−17.91647286

342 = a²

switch sides:

for x² = f(a) the solutions are x = √ f(a) and - √ f(a)

therefore:

√ 342 = 18

-√ 342 = - 18

a = 18 and a = - 18

hope this helps!

Option D: The distance between the two points is 13 units

Explanation:

It is given that the two points are $(-5,-2)$ and $(8,-3)$

We need to determine the distance between the two points.

It is also given that the distance between the two points can be determined using the formula,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substituting the points $(-5,-2)$ and $(8,-3)$ for the coordinates $(x_1,y_1)$ and $(x_2,y_2)$

Thus, we get,

$d=\sqrt{(8-(-5))^2+(-3-(-2))^2}$

Simplifying, we have,

$d=\sqrt{(8+5)^2+(-3+2)^2}$

Adding the terms, we get,

$d=\sqrt{(13)^2+(-1)^2}$

Squaring the terms, we have,

$d=\sqrt{169+1}$

Adding the terms, we get,

$d=\sqrt{170}$

Simplifying and rounding off the value to the nearest tenth, we have,

$d=13.0 \ units$

Hence, the distance between the two points is 13 units.

Therefore, Option D is the correct answer.

What are the possible values of x in 8x2 + 4x = -1?

Westkost [7]

Answer:

The possible values of x are:

x= $\frac{-1+\sqrt{3}}{4} \,\,or\,\, x= 0.18$

and

x= $\frac{-1-\sqrt{3}}{4} \,\, or \,\, x= -0.68$

Step-by-step explanation:

$8x^2+4x+1=0$

Using Quadratic formula to solve this equation:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\a = 8 \,\, b = 4\,\, c = -1\\Putting \,\, values \,\, in \,\, the\,\, equation\\x= \frac{-4\pm\sqrt{(4)^2-4(8)(-1)}}{2(8)}\\x= \frac{-4\pm\sqrt{16+32}}{16}\\x= \frac{-4\pm\sqrt{48}}{16}\\x= \frac{-4+ \sqrt{48}}{16} \,\, and \,\, x= \frac{-4- \sqrt{48}}{16}\\x= \frac{-1+ \sqrt{3}}{4} \,\, and \,\, x= \frac{-1- \sqrt{3}}{4}$

The possible values of x are:

x= $\frac{-1+\sqrt{3}}{4} \,\,or\,\, x= 0.18$

and

x= $\frac{-1-\sqrt{3}}{4} \,\, or \,\, x= -0.68$

Four brother each bought two hotdogs and a bag of chips at the football

jeyben [28]

Answer:

A-$1.65

Step-by-step explanation:

You multiply 1.25 by 4 because each brother bought a bag of chips. Then you subtract that by the total and get $13.20 you divide that by 8 hot dog because each brother got 2 hot dogs. By dividing 8 by the left over amount from subtracting the chips you get how much each hot dog is worth.
