Answer:

Step-by-step explanation:

2(2x + 1) = (2)(2x) + (2)(1) = 4x + 2 → A

<em>used distributive property</em>

2(2x + 1) = 2(1 + 2x) → B

<em>used commutative property</em>

2(2x + 1) = (2x + 1) + (2x + 1) = 2x + 1 + 2x + 1 → D

2(2x + 1) = 4x + 2 = x + x + x + x + 1 + 1 → E

Multiply 1300 mm by 800 mm to get 1040000 mm. Then convert this to meters. 1 meter=1000 mm. Therefore, 1040000 mm is the same as 1040 meters.

Answer:

$\$16.625\approx \$16.30$

Step-by-step explanation:

Original price = $17.50

Discount = 5%

Find the amount of discount (in dollars):

$5\%=0.05\\ \\\$17.50\cdot 0.05=\$0.875$

Now, the sale price is

$\text{Sale Price}=\text{Original Price}-\text{Discount}\\ \\\text{Sale Price}=\$17.50-\$0.875\\ \\\text{Sale Price}=\$16.625\approx \$16.30$
