2(x^2+3) = 2(x^2)+6 = 2(16)+6 or 38
4x = 16
3y = 18

therefore,

4(4)+3(6)-2(4^2+3)= (16+18)-38 = 34-38 = -4

hope this helps.

miguel is 5ft 10 inches tall On a sunny day he casts a shadow of 4ft 2 inches long. At the same time, a nearby electric tower ca

Alex787 [66]

Given:
Miguel's height:
Actual = 5 feet 10 inches
Shadow = 4 feet 2 inches

Tower's height
Actual = x
Shadow = 8 feet 9 inches

First, we need to convert the height into inches to avoid confusion.
1 foot = 12 inches.
Miguel:
5 ft x 12in/ft = 60 inches + 10 inches = 70 inches ACTUAL
4 ft x 12in/ft = 48 inches + 2 inches = 50 inches SHADOW

Tower:
8 ft x 12in/ft = 96 inches + 9 inches = 105 inches SHADOW

Ratio of Actual to shadow:
Miguel: 70 : 50
Tower: x : 105

70 : 50 = x : 105
70*105 = 50x
7350 = 50x
7350 / 50 = x
147 = x

Actual height of the tower is 147 inches or 12 feet 3 inches long.

To check:
Miguel : 70 / 50 = 1.40
Tower : 147 / 105 = 1.40

Target is having a Back to School sale where all polo shirts are discounted by 20%. Joshua wants to buy five shirts: two cost $1

Sholpan [36]

Answer:

Both cases will give the same price

Step-by-step explanation:

The total purchase that Joshua do will be:

2* $10.98 + 1 * $11.50 + 2* $15.99 = $65.44

Let's compare the price for both scenario

1. If the tax added before discount

taxed price $65.44 * (100+6.5)% =$69.6936

discounted price= $69.6936* (100-20)%= $55.75488

2. If the tax added after the discount

discounted price= $65.44 * (100-20)%= $52.352

taxed price $52.352 * (100+6.5%) = 55.75488

Both prices will be the same since the operation in this calculation is only multiplication.
