(b) since a negative number added to a positive one it will be positive

Answer:

2x² + 5x - 12

steps:

→ (x+4)(2x-3)

By distributive method:

→ (x)(2x) +4(2x) +x(-3) +4(-3)

simplifying:

→ 2x² + 8x - 3x - 12

final answer:

→ 2x² + 5x - 12

Any straight line segment can be extended indefinitely and straight line segment can be drawn between any two points can apply. Therefore, options A and D are the correct answers.

"Euclidean geometry is the study of plane and solid figures on the basis of axioms and theorems employed by the Greek mathematician Euclid"

As per the five basic postulates of Euclidean geometry

A straight line can be drawn from any point to another point.

A terminated line can be further produced indefinitely.

A circle can be drawn with any Centre and any radius.

All right angles are equal to one another.

If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles , then the two lines inevitably must intersect each other on that side if extended far enough.

Therefore, options A and D are the correct answers.

Step-by-step explanation:

Answer: B: 7.14 in²

Step-by-step explanation:

Area of the square: 2x2 = 4in²

Area of the circle: πr² = 3.14 x 1² = 3.14

add them both to get the composite area:

Step-by-step explanation:

the extreme values of a function happen at the zeros of the first derivation of that function.

f(t) = -16t² + 72t

f'(t) = -2×16t + 72 = -32t + 72

0 = -32t + 72

32t = 72

t = 72/32 = 2.25 seconds

f(2.25) = -16(2.25)² + 72×2.25 = -16×5.0625 + 72×2.25 =

= -81 + 162 = 81 ft

so, the rocket reaches its maximum height of 81 ft after 2.25 seconds of flight.

Answer:

If Its 7 in diameter than the answer is 21.98 if it is radius than it is 153.86

Step-by-step explanation:

Answer:

Solution:

Radius of a circle = 7 in

We know that

Circumference of a circle = 2πrSubstituting the values

= 2 × π × 7

= 14π

= 43.9823 ≈ 43.98 in

Therefore, the circumference of a circle is 43.98 in.

Step-by-step explanation:

if your buying 3 dozen of donuts, the total cost would be by doing 7x3

Solution:

It should be noted:

Let's reread the sentence carefully.

Eric sells donuts for $7    per dozen.

                                   ↥           ↥

                                  $7     1 dozen

The equation created: $7 = 1 dozen

If x dozen doughnuts were sold, equation: $7x = t = x dozen

Thus, the equation that can determine the total cost, t, for x dozen of donuts is $7x = t.

Rectangle: 6*15=90

Inner Trapezoid: 6*4=24

Triangles: 4*2=8/2=4*2=8

Answer:

the last one

Step-by-step explanation:

Answer:

Question (a)

Surface area of a cube = [tex]6x^2[/tex]   (where [tex]x[/tex] is an edge length)

⇒ surface area = 6 × 3²

                         = 6 × 3 × 3

                         = 6 × 9

                         = 54 in²

Volume of a cube = [tex]x^3[/tex]   (where [tex]x[/tex] is an edge length)

⇒ volume = 3³

                 = 3 × 3 × 3

                 = 27 in³

Question (b)

To find the area of a dilated figure, simply multiply the original area by the scale factor squared:

Surface area = [tex]6x^2[/tex] × sf²  

                      = 54 × 0.5²

                      = 13.5 in²

To find the volume of a dilated figure, simply multiply the original volume by the scale factor cubed:

Surface area = [tex]x^3[/tex] × sf³

                      = 27 × 0.5³

                      = 3.375 in³

Step-by-step explanation:

divide by the coefficient on both sides of then equation.

The hydroxide ion concentration in a solution of nh3 with a poh of 4.65 is 2.2387×10⁻⁵ M.

The pH scale, which originally stood for "potential of hydrogen," is used to describe the acidity or basicity of aqueous solutions. The pH of acidic solutions is lower than that of basic or alkaline solutions.

Hydronium ions concentration of the solution with a pH value of 4.65.

[tex]pH = -\rm log[H_3O^+]\\\\4.65 = -log[H_3O^+]\\\\\text{Taking Antilog}\\\\10^{-4.65}=[H_3O^+]\\[/tex]

[tex][H_3O^+] = 2.2387 \times 10^{-5} M[/tex]

Now, we know that the Hydroxide ions concentration of the solution with pOH value of 4.65. Therefore,

[tex]pOH = -\rm log[OH^-]\\\\4.65 = -log[OH^-]\\\\\text{Taking Antilog}\\\\10^{-4.65}=[OH^-][/tex]

[tex][OH^-]=2.2387 \times 10^{-5}\ M[/tex]

Hence, the hydroxide ion concentration in a solution of nh3 with a poh of 4.65 is 2.2387×10⁻⁵ M.

The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the equation for Bella:

c = 0.1n + 150

Where C is the monthly cost for n checks.

For Justin:

1.2 = 3k

k = 0.4

C = 0.4n

To have the same cost:

0.1n + 150 = 0.4n

n = 500

c = 0.4(500) = 200

The cost would be the same for Justin and Bella if 500 checks are sold, costing about $200.
