Answer:

17 7/9 or 17.7

Step-by-step explanation:

The Answer is

A.(x+12)2 = -60

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The formula for (a + b)² = a² + 2ab + b²

The equation x² + 24x + 60 = 0 in the form (x + p)² = q is

(x + 12)² = 84

Option A is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

x² + 24x + 60 = 0

We can write this as,

x² + 2 x 12 x (x) + 60 = 0

The formula for (a + b)² = a² + 2ab + b²

Add 144 on both sides.

x² + 2 x 12 x (x) + 60  + 144 = 0 + 144

x² + 2 x 12 x (x) + 144 + 60 = 144

[ 12² = 144 ]

Subtract 60 on both sides.

x² + 2 x 12 x (x) + 144 = 144 - 60

x² + 2 x 12 x (x) + 12² = 84

(x + 12)² = 84

Thus,

The equation x² + 24x + 60 = 0 in the form (x + p)² = q is

(x + 12)² = 84

Option A is the correct answer.

Answer: 2n - 64

Step-by-step explanation:

If the vairiable n describes the unknown number, and there is twice the number, then we can use the term 2n.

We also have 64 less then that number, and less means to subtract. Therefore, the equation is 2n - 64.

Answer:

2n-64

Step-by-step explanation:

I believe this is the correct answer (Not exactly sure to be honest)

Twice a number means to multiply by 2, so you use the variable (n) and multiply it by 2. For subtracting 64, I believe you usually put it after the (2n) portion of the equation. You may have to flip it though, equation order is important and it's been a while since I've done these so apologies if it's wrong! Good Luck!

Answer:

x=30, y=5

Step-by-step explanation:

in the first triangle, with 3 congruent angles, Since their angles are congruent l, there sides are also as well. So 8y=40 y=5. This is a right triangle so angle x and the adjacent red angle both form 90 degrees. Since the red angle is a equal angular triangle. It measures 60 degrees so 60+x=90 x=30

Answer:

Step-by-step explanation:

Lara has $12 in quarters.

4 quarters make a dollar.

To find the number of quarters she has therefore, you need to multiply the $12 by the 4 quarters in a dollar to find out the number of quarters in $12.

= 12 * 4

= 48 quarters

Answer:

constant monomial

Step-by-step explanation:

The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.

The given expression is a constant monomial. Therefore, option A is the correct answer.

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Here given expression is 9.

A constant monomial is a term with only a constant number. There is no variable in a constant monomial.

So, 9 is a constant monomial.

The given expression is a constant monomial. Therefore, option A is the correct answer.

Answer:

4<x<12

Step-by-step explanation:

8.0+4.0=12.0

8.0-4.0=4.0 or 4

The rules of triangles is that it must be less than the sum you had when you first added 8.0and 4.0 which was 12

So therefore , 4< x < 12

Answer:

h=12 + c=20

Step-by-step explanation:

a^2+b^2=c^2

9^2+h^2=15^2

15^2-9^2=h^2

225-81=h^2

144=h^2

[tex]\sqrt{144}[/tex] = h

12=h

a^2+b^2=c^2

16^2 + 12^2 = c^2

256+144=c^2

400=c^2

[tex]\sqrt{400}[/tex] = c

26.) 5/2 = d-2/4

cross multiply:

5×4=2(d-2)

20= 2(d-2) divide both sides by 2

20÷2 = 2(d-2)÷2

10= d-2 exchange places with d and 10 and change signs

-d= -2-10

-d=-12 change the sign on both sides when the variable is negative.

d=12

Answer:

Step-by-step explanation:

Length : Breadth : height = 3 : 4 : 6

Length = 3x

Breadth = 4x

Height = 6x

Volume of cuboid = 576 sq.cm

length * breadth * height = 576

3x * 4x * 6x = 576

       72x³   = 576

             x³ = 576/72

            x³ =   8

            x³ = 2³

x = 2

Length = 3*2 = 6 cm

Breadth = 4* 2 = 8 cm

Height = 6*2 = 12 cm

Total surface area = 2*(lb + bh + hl)

                             = 2 * (6*8 + 8*12 + 12*6)

                            = 2 * (48 + 96 + 72)

                            = 2 * 216

                            = 432 sq.cm

Answer:

BD=24

Step-by-step explanation:

I assigned my unkown sides of the triangles as x and y, where x = BD and y =AD.

I used pythagoras' theorem to find expressions for the the sides of the triangles in terms of x and y.

Both expressions had the term x^2 in them, so I equated expressions of x^2

From there i rearranged to find y.

Using my value of y, I found x.
