How does 2(3m+6) compare to 5(2m+3)-4m when m is a postive intenger .

i might be wrong but you have to do proportions, i got 45 minute

Step-by-step explanation:

set it,it up by 30 minutes over 4 miles and x over 6 miles then you multiply by 6 and 30 which is 180 then divide by 4 and i got 45

Step-by-step explanation:

The options are not given. So, I will solve from scratch

Given

[tex]\frac{secx-1}{tan x}= \frac{tanx}{secx+1}[/tex]

Required

Prove

Multiply the right-hand side by [tex]\frac{secx + 1}{secx + 1}[/tex]

[tex]\frac{secx-1}{tan x} * \frac{secx + 1}{secx + 1}= \frac{tanx}{secx+1}[/tex]

Apply difference of two squares on the numerator

[tex]\frac{sec^2 x - 1}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

In trigonometry:

[tex]tan^2x = sec^2x - 1[/tex]

So, we have:

[tex]\frac{tan^2 x}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

[tex]\frac{tan x * tan x}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

tan x cancels out

[tex]\frac{tan x}{secx + 1} =\frac{tanx}{secx+1}[/tex]

Answer:

2x + 21

Step-by-step explanation:

Given :

Plant 1 : production level) 5x + 17

Plant 2 : production level = 3x - 4

To how much more plant 1 produces than plant 2 ; subtract production of plant 2 from plant 1

(5x + 17) - (3x - 4)

Open the bracket

5x + 17 - 3x + 4

5x - 3x + 17 + 4

2x + 21

Answer:

18 stamps

Step-by-step explanation:

3/5(30) = 90/5 = 18

Answer:

Step-by-step explanation:

The chart tells you Zack has 30 stamps in total.

3/5 are animal stamps.

So you do

30 x 3/5 = 90 / 5 = 18

OR

30 / 5 x 3 = 6 x 3 = 18

Hope that helps!

Answer:

£9.80

Step-by-step explanation:

The computation of the total value is shown below:

Given that

The value of 20p coins is £2.80

So the value of 50p would be

= £2.80 × 50 ÷ 20

= £7

Now the total value is

= £2.80 +  £7

= £9.80

Answer: Charity is 36 years old today.

Step-by-step explanation:

Let x = Present age of daughter.

Age of Charity = 4x

Age of her husband = 4x+6

After 10 years,

Age of daughter = x+10

Age of Charity = 4x+10

Age of her husband = 4x+6+10=4x+16

As per given,

[tex]x+10+4x+10+4x+16=117[/tex]

[tex]9x+36=117\\\\ 9x=117-36\\\\ 9x=81\\\\ x=9[/tex]

Present age of Charity = 4(9)=36 years

Hence, Charity is 36 years old today.

Step-by-step explanation:

Answer:

Approximately [tex]5.7[/tex] inches

Step-by-step explanation:

The crossbar and two given lengths form a right triangle. We know this because we see a right angle marked on the diagram in between the two given sides.

In this case, we have a right triangle with legs of [tex]4[/tex] and [tex]4[/tex], and we need to find the hypotenuse. By the Pythagorean Theorem ([tex]a^{2} +b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse), we get:

[tex]4^{2} +4^{2} =c^{2}[/tex]

[tex]16+16=c^{2}[/tex] (Evaluate exponents)

[tex]32=c^{2}[/tex] (Combine like terms)

[tex]\sqrt{32}=\sqrt{c^{2}}[/tex] (Take the square root of both sides of the equation to get rid of [tex]c[/tex]'s exponent)

[tex]c=4\sqrt{2} ,c=-4\sqrt{2}[/tex]

The latter solution is an extraneous solution because the side lengths of a triangle cannot be negative. Therefore, the answer is [tex]4\sqrt{2} \approx 5.7[/tex] inches. Hope this helps!

Answer:

DC

Step-by-step explanation:

DC

It’s opposite the smallest angle.

The function f is defined by f(x)=x^2+3x-10 If f(x+5)=x^2+kx+30,

k= Find the smallest zero of f(x+5),

x= By definition, the zero of a polynomial function is a number a such that f(a)=0.

For quadratic equation, the zeros can be found on equalizing f to 0. First, f(x+5)=(x+5)²+3(x+5)-10=x²+10x+25+3x+15-10=x²+13x+30,

and it is told that If f(x+5)=x^2+kx+30 = x²+13x+30,

it implies k=13, so let’s find the zeros. x²+13x+30=0 is to solve: D= 13²-4x1x30=169-120=49, sqrt49=7,

so x=-13-7 / 2=-20/2 = -10, and x= -13+7/ 2 = -6 /2= -3. Obviously, we know that -10< -3, so the smallest zero is -10.
