$\boxed{ 26m + 12}$

Step-by-step explanation:

$3(7m + 4) + 5m$

Distribute:

$= (3) (7m) + (3) (4) + 5m$

$= 21m + 12 + 5m$

Combine Like Terms:

$= 21m + 12 + 5m$

$= ( 21m + 5m) + (12)$

$= 26m + 12$

Can someone please help me answer this?

Answer:

Step-by-step explanation:

If you don't understand some steps, comment it for me please.

1. Find diagonal.

d = 2r

d = 2(9)

d = 18

2. Find length of square.

each length of square = x

$x : 18 = 1 : \sqrt{2}$

$\frac{x}{18} = \frac{1}{\sqrt{2} }$

$\sqrt{2}x = 18$

$x = \frac{18}{\sqrt{2} } = 9\sqrt{2}$

3. Find area of circle and square.

Area for circle

$A = \pi r^2$

$A = \pi (9)^2$

$A = 81\pi = 254.4690...$

Area for square

$A = (length)^2$

$A = (9\sqrt{2})^2$

$A = 162$

4. Subtract area of circle to area of square.

254.4690... - 162 = 92.4690...

5. Find the shaded region.

92.4690... / 4 = 23.1172...

Rounded to the nearest hundredth = 23.12

Cary claimed that the expression − 5 + m − 5 + m is negative. Determine whether Cary's claim is always true, sometimes true, or

atroni [7]

Answer:

The given Expression is sometimes true.

Step-by-step explanation:

from the question,

The given expression by Cary is $-5 + m -5+ m$ .

So, solving the expression we get

⇒ $-10+2m$

Let $m$ is an integer.

Whenever,

(a) $m < 5$ { $m = 4,3,2,1,0,-1,-2.......................$ }

The given Expression always gives negative value.

(b) $m\geq 5$ { $m = 5,6,7,8,9.......................$ }

The given Expression always gives positive value.

Here, we get that the given Expression is not providing the Negative value always, that's why it is not always true and can't be never true.

Hence,

According to Cary's claimantion the given Expression is sometimes true.
