Answer:

Step-by-step explanation:

X^2+7x+63=63

<=> x^2+7x=63-63=0

<=> X(x+7)=0

<=> x1=0

X2=-7

Answer:

0 or -7

Step-by-step explanation:

     x² + 7x + 63 = 63

⇔ x² + 7x + 63 - 63 = 0

⇔ x² + 7x = 0

⇔ x(x + 7) = 0

So either:  x = 0

            or x + 7 = 0 ⇔ x = -7

Terry is building a tool shed with a 90 square foot base and a length that is three more than twice the width. This can be model
Lilit [14]

Answer:

l = 15 feet

Step-by-step explanation:

l = 2w + 3

First you solve for the width(w)

(2w+15) (w-6) = 0

This means

2w+15=0 OR. w-6=0

First let’s solve 2w+15=0

2w = -15

w = -7.5

Width can’t be negative so that can’t be the answer. So we look at the second equation w-6=0

w= 6

Since we found the width now we can find the length by using the formula l = 2w + 3

= 2(6) + 3

= 12 + 3

= 15 feet

You can check this by using the given area which is 90.

A = lw = 15*6 = 90

What is the best approximation for the area of this circle?
butalik [34]

Area =113.0ft^2 . Correct option is D) 113.0 ft² .

<u>Step-by-step explanation:</u>

Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:

We know that area of circle = \pi r^2 , We have following parameters as

Radius = r = 6 ft\\\pi = 3.14\\Area= \pi r^2 = ?

So , Area of circle is

⇒ Area =\pi r^2

⇒ Area =(3.14) (6)^2

⇒ Area =(3.14) (36)^

⇒ Area =113.04ft^2

On Rounding off

⇒ Area =113.0ft^2

Therefore , Area =113.0ft^2 . Correct option is D) 113.0 ft² .

Define the concept of an angle and show how it should be indicated in Math (notation). Mention at least two ways.​
Vedmedyk [2.9K]

An angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.

An angle is denoted by the angle symbol ∠ which is then being followed by three letters that will represent the points that form an angle.

Lets say for example, the expression ∠ABC will mean that “the angle is formed by the points A, B and C”

where the vertex of the angle is at the point B as it is in the middle.

Angles can also be of different types like:

An Acute Angle which means an angle is less than 90 degrees.

A Right Angle which means an angle which is exactly 90 degrees.

An Obtuse Angle which is an angle more than 90 degrees and less than 180 degrees.

A Straight Angle which is an angle that is exactly 180 degrees.

And a Reflex Angle which is an angle greater than 180 degrees and less than 360 degrees.

Therefore, an angle is denoted by the angle symbol ∠ and the three letters representing the name of the angle.
