Answer:

14x-12

Step-by-step explanation:

Simplify (2x-3)(7x+4).

Expand the brackets. Remember brackets mean to multiply.

We multiply the 2x and the 7x to get 14x and we multiply the -3 by 4 to get -12 as shown below;

(2x-3)(7x+4)

14x-12

(x + 7)(x + 10) = what is the answer
ch4aika [34]

We can use FOIL to solve.

(x + 7)(x + 10)

(x * x) + (x * 7) + (7 * x) + (7 * 10)

x² + 7x + 7x + 70

x² + 14x + 70

Best of Luck!

PLEASEEEEE HELP!! BRAINLIEST!!
ycow [4]

Step-by-step explanation:

Rate of change = final - initial / time(in years)

= 41 - 43 / 2014 - 2012

= - 2 / 2

<u>Rate of change</u> = <u>- 1</u>

Therefore, the number of employees with health care benefits reduced by 1 person per year between 2012 - 2014 in response to policy changes.

I need help very important
siniylev [52]

Answer:

∠ EFG = 83°, ∠ GCE = 97°

Step-by-step explanation:

Since FE and FG are tangents to the circle then

∠ FGC and ∠ FEC are right angles

The sum of the angles in quadrilateral CEFG = 360°

Sum the 4 angles and equate to 360

3x + 11 + 90 + 5x - 23 + 90 = 360, that is

8x + 168 = 360 ( subtract 168 from both sides )

8x = 192 ( divide both sides by 8 )

x = 24

Thus

∠ EFG = 3x + 11 = 3(24) + 11 = 72 + 11 = 83°

∠ GCE = 5x - 23 = 5(24) - 23 = 120 - 23 = 97°

Mrs. Miller sells a house for 179,000. If she earns a commission of 6%, how much money does she earn? ( can u also show me how u
Kryger [21]

Hi there!

Mrs. Miller earns a commission of 6% of 179,000

The word "of" is the same thing as a multiplication sign.

6% of 179,000 = 6% × 179,000

6% = 0.06

6% × 179,000 = 0.06 × 179,000

0.06 × 179,000 = 10,740


Your answer is: Mrs. Miller earns $10,740 of commission.


There you go! I really hope this helped, if there's anything just let me know! :)
