9514 1404 393

Answer:

  31.41 ft²

Step-by-step explanation:

Heron's formula is useful when you have the three side lengths.

  A = √(s(s -a)(s -b)(s -c)) . . . . sides are a, b, c and s = (a+b+c)/2

Using the given side lengths, we have ...

  s = (8 +8.4 +13.5)/2 = 29.9/2 = 14.95

  A = √(14.95(14.95 -8)(14.95 -8.4)(14.95 -13.5)) = √(14.95×6.95×6.55×1.45)

  A = √986.81399375 ≈ 31.41 . . . . square feet

Hello there! So, this is a quadrilateral and quadrilaterals equal 360 degrees. Let’s combine like terms to start off. 39x + 9 = 360. First, let’s subtract 9 from both sides to get 39x = 351. Next, divide each side y 39 to isolate the “x”. When you do that, x = 9. Now, let’s plug in the values for each, when you do, here are the final answers.

x = 9
E = 75 degrees
F = 91 degrees
G = 89 degrees
H = 105 degrees

Those are all of the angle measurements, but it wants the measurement of angle H. Therefore, that angle measurement is 105 degrees.

A Luxury of Furniture at a store sells couches for $4,000,Reclining Chairs for $2,040 and loveseats for $2,800. This Luxury line
Kamila [148]
<span><span>1.       </span>Couches = $4 000
Reclining Chairs = $ 2 040
=> Loveseats = $2 800
So, the luxury store went on sale that makes each prices divided 4
=> Couches = 4 000 / 4 = 1 000 dollars
=> 2 couches = 2 000 dollars
=> reclining chairs = 2 040 / 4 =510 dollars
=> 1 reclining chair = 510 dollars
=> Loveseats = 2 800 / 4 = 700 dollars
=> 3 loveseats = 2 100 dollars</span>

Question 4 of 32 Jacob is a construction worker who earns a yearly income given by the expression 2000x + 3000, where x is the n
ELEN [110]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the expression :

Jacob's yearly income :

2000x + 3000 ; x = number of hours worked per week.

Carlos income :

3800x - 40000

Managers prediction = 35

Jacob.: 2000(35) + 3000 = 73000

Carlos : 3800(35) - 40000 = 93000

Carlos will earn more than Jacob given the manager's prediction.

Number of hours required so they can earn the same amount :

2000x + 3000 = 3800x - 40000

3000 + 40000 = 3800x - 2000x

43000 = 1800x

x = 43000/1800

x = 23.88

x = 24 hours

Use the distributive property to remove the parentheses.
sergij07 [2.7K]

Answer:

3+2x

Step-by-step explanation:

Distribute the equation out.

1/4(12+8x)

(1/4*12)+(1/4*8x)

Multiple those out to get a new equation

3+2x

You cannot add those together because of the variable. Theres no way of knowing what x equals so this is as far as you can go therefor making the answer 3+2x
