Multiplied by the cross
4/15 = x /75
15•x=4•75
15x=300
x= 300 : 15
x=20
t/9 = 35/6
9•35 = t•6
315 =6t
315 : 6 = t
52,5 = t
Answer:
Answer A is correct.
Step-by-step explanation:
Please note the difference beteen f(x+3) and f(3).
So f(x + 3) means, where you see x in the equation, you substitute x+3. (This is a recursive entry).
f(x)= 2x² - 3
f(x)= -3 + 2x²
f(x)= -3 + 2* (x+3)²
f(x)= -3 + 2* (x+3) * (x+3)
f(x)= -3 + 2* (x² + 3x + 3x + 9)
f(x)= -3 + 2* (x² + 6x + 9)
f(x)= -3 + 2x² + 12x + 18
f(x)= 2x² + 12x + 18 -3
f(x)= 2x² + 12x + 15
So answer A is the correct answer
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
First let's establish that the problem requires the border to be as long as the total perimeter of the rectangular bulletin board.
Therefore:
Total length of border = Perimeter of rectangular bulletin board
As a rectangle has a total of four sides with two equivalent longer sides and two equivalent shorter sides, we must multiply the value of each of the two sides by two.
Total length of border = 2 ( 2 ) + 2 ( 4 )
Total length of border = 4 + 8
Total length of border = 12 feet
12 > 10
ANSWER:
Therefore, 10 feet of border isn't enough.

Step-by-step explanation:
Remark
The ratio should be 10 : 19
Given
Flag Ratio: 225 : 505
Break the dimensions into prime factors.
225: 15 * 15 = 3*5 * 3*5
505: 5 * 101
Conclusion
101 is prime so this dimension cannot be broken down any further
The fives cancel out. The dimensions of this flag are in the ratio of 45/101 which is 0.4455
10/19 = 0.5263
I would say this is reasonably close.
7-15= -8
so -8 degrees celsius
