Actually Welcome to the Concept of the Factorisation.

Since here both are the roots of the quadratic equation in the factor form, hence

equate them to zero, to get the value of x

hence,

2x-9 = 0

===> x = 9/2

and

3x+5=0

===> x = -5/3

Answer: ............

Step-by-step explanation:

Answer:

simplify to:

6-32768/-60

simplify more

-32762/-60

take away the negatives

32762/60

simplify the fraction

16381/30

keep going till you get the answer

Answer:

67

Step-by-step explanation:

Equilateral triangles are triangles whose all sides and angles are equal.

Since the above given triangle has 3 equal sides it is an equilateral triangle.

So, the three angles of this triangle can be 3x.

Which means :

[tex] =\tt 3x = 180[/tex]

[tex] =\tt x = \frac{180}{3} [/tex]

[tex]\hookrightarrow \tt \color{plum}x = 60°[/tex]

▪︎Therefore, x = 60°

yeah its probably done well

Step-by-step explanation:

Answer:

-46/45

Step-by-step explanation:

-2/9 + (-4/5)

can be re-written as

-2/9 - 4/5

which equals -46/45

if they want you to answer in decimal form, it will be -1.02

Answer:

A. (a + b)(b + c)

Step-by-step explanation:

b( a + b ) + bc + ac

b( a + b ) + c ( b + a )

= (a + b)(b + c)

hope it helps!

Answer:

A

Step-by-step explanation:

a(b+c)+bc+bb

a(b+c)+b(c+b)

(b+c)(a+b)

Answer:

sum of all angles =180

15° + 25° +(39+x) =180°

40° + 39 +x = 180

79° +x =180

x = 180 - 79

x. = 101

complete angel = 39 +x

= 39 + 101

= 140

Answer:

C equals 48

Step-by-step explanation:

You add the two angles you have and take that answer and subtract it from 180 and that is the missing angle measure

Answer:

[tex]\frac{1}{4} = 2^{-2}[/tex]

[tex]\frac{1}{100} = 10^{-2}[/tex]

Step-by-step explanation:

The question is poorly formatted. However, I am able to get:

1. 1/4 and 2. 1/100

Required

Write as an expression of negative expression

1. 1/4.

Express 4 as 2^2

[tex]\frac{1}{4} = \frac{1}{2^2}[/tex]

Apply

law of indices [tex](\frac{1}{a^b} = a^{-b})[/tex]

[tex]\frac{1}{4} = 2^{-2}[/tex]

2. 1/100.

Express 100 as 4^2

[tex]\frac{1}{100} = \frac{1}{10^2}[/tex]

Apply law of indices [tex](\frac{1}{a^b} = a^{-b})[/tex]

[tex]\frac{1}{100} = 10^{-2}[/tex]

Answer:

There is a vertical asymptote at x = 4 because lim g(x) = ∝ and lim g(x) = -∝

Answer:

2/5 < 1/2

Step-by-step explanation:

First, find the LCM for both denominators because you can't multiply 2 to get to 5. The LCM of 5 and 2 are 10, so you put that as their denominator. Then you have to think what you multiplied by 5 or 2 to get 10. For 2/5, you multiplied 5 by 2 to get 10, so multiply the numerator by 2 too. For 1/2, you multiplied 2 by 5 to get 10, so multiply the numerator by 5. Now, you will have 4/10 and 5/10. It's pretty obvious that 5/10 is bigger than 4/10, so the correct answer is 2/5 < 1/2

if wrong i'm sorry

Answer: 42 feet

Step-by-step explanation:

Let the length be x

Therefore, width = 2/3x

Area = Length × Width

Therefore, x × 2/3x = 1176

2/3x² = 1176

Divide both side by 2/3

x² = 1176 ÷ 2/3

x² = 1176 × 3/2

x² = 1764

x = ✓1764

x = 42

The length is 42 feet

Answer:

112.46 yd³

Step-by-step explanation:

1 inch = 0.0278 yds

1 feet = 0.333 yd

Thickness = 4 inches = (4 * 0.0278) = 0.1112 yds

Width = 3 feets = (3 * 0.333) = 0.999 yds

Length = 40 feets = (40 * 0.333) = 13.32 yds

Volume of sidewalk :

Thickness * Width * Length

0.1112 * 0.999 * 13.32 = 1.479702816 yd³

1 yd³ of cement = $76

Cost :

1.479702816 yd³ * $76

= 112.457414016

= 112.46 yd³

Answer:

22.4

Step-by-step explanation:

7% of the cost is 22.4

Answer:

−2x−28

Step-by-step explanation:

Distribute:

=(−4)(x)+(−4)(6)+(2)(x)+(2)(−2)

=−4x+−24+2x+−4

Combine Like Terms:

=−4x+−24+2x+−4

=(−4x+2x)+(−24+−4)

= −2x - 28

Answer:

120

Step-by-step explanation:

Answer:

the answer is C) 120

Step-by-step explanation:

cos4A-sin4A=2cos2A-1

proved below.

Step-by-step explanation:

Given:

cos^4A-sin^4A=2cos^2A-1

LHS=cos^4A-sin^4A

=[cos^2A]^2-[sin^2A]^2

=[cos^2A+sin^2A][cos^2A-sin^2A]

=[1][cos^2A-(1-cos^2A)] [ cos^2A+sin^2A=1]

=[cos^2A-1+cos^2A]

=2cos^2A-1

=RHS.
