Answer:

x=+4, x= -4

Step-by-step explanation:

the solutions to the quadratic equation  4x^2= 64

To solve the quadratic equation , solve the equation for x

4x^2= 64

Divide both sides by 4

x^2= 16

To eliminate square from x , take square root on both sides

\sqrt{x^2} =\sqrt{16}

When we take square root we put +-

x=+-4

x=+4, x= -4

X=4 or X=-4 because 4(4)^2 does =64

A multiple choice test consists of six questions, each of which has four choices. Each question has exactly one correct answer.

To get 4 or fewer correct, at least 2 answers have to be wrong. And the probability of that is:
3/4 x 3/4=9/16
1-9/16=probability that 4 or fewer are correct=7/16 ☺☺☺☺

Through: (1,5), perp. to y=-1/10x + 3<br> pls help
Sedbober [7]
First to get the equation you knew to understand one thing about perpendicular lines. The slope of the line is the opposite reciprocal of the perpendicular lines or the new slope is m = 10.

Then you use the formula
y = mx + b
you plug in your values from the point and the new slope.
(1,5) with new slope m
5= 10(1)+b
5-10=b
-5 = b
then make your new equation
y = 10x -5
that's your line that goes through point (1,5) and is perpendicular to the line given

8 Select the correct answer from each drop-down menu. Some of the images in the diagram are images of polygon 1 from similarity
makkiz [27]

It should be noted that Polygon 3 and polygon 4 are similar to polygon 1.

<h3>What exactly is polygon?</h3>

In geometry, it should be noted that a polygon is a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.

In this case, the bounded plane region, the bounding circuit, may be called a polygon. Also, a similarity transformation is the conformal mapping whose transformation matrix are identical.

In this case, it should be noted that Polygon 3 and polygon 4 are similar to polygon 1.

What is the measure of <br> a) 264°<br> b) 132°<br> c) 71°<br> d) 66°
Yuki888 [10]

The answer is 132° because there angle CDE is 87° so you know it's more of that. And, 264° is way too wide.
