Answer:
<u>For</u><u> </u><u>A</u>
• The equation above has a common bracket "(x + 1)". So, let's first factorise out that bracket:
• now in the second bracket, the common factor is x and 2.
• Final answer;
<u>For</u><u> </u><u>B</u>
• In the equation, the common bracket is (x + 2).
So let's first factorise it out:
• In the second major bracket, the common bracket is (x - 1). so factorise it out:
• Final answer:
Answer:
tax: $18.9
total cost: $333.9
Step-by-step explanation:
$315 × 0.06 = 18.9
18.9 + 315 = 333.9
btw you can also do "315 × 1.06" to get the total cost without having to manually add the tax
Answer:
A = 119 units²
Step-by-step explanation:
side of square is (12√2)sin45 = 12
The portion of the diagonal that is NOT octagon is
12√2 - 12
There are four corner triangles. The sum of their areas is
(12√2 - 12)²
Area of the octagon is area of the square minus four corner triangle areas.
A = 12² - (12√2 - 12)²
A = 119.2935...
I think the answer to your question is A, hope this helps
