If a were to be doubled, and be 10 more than the initial number, the value of a would also have to be 10 because when it is doubled, it becomes 20, and you can see that adding 10 to it will also make it be 20. The value of a would have to be 10.
Answer:
The first one is $41,400. The second one is 3,600,000 acres.
Step-by-step explanation:
Given ,
AB = BC
BC = CA
CA = 6 cm
This is an equilateral triangle as the first side is equal to the second side and the third side is equal to the second side which is equal to the first side . As all the sides are equal to 6 cm , this triangle is said to be an equilateral triangle .
∴ Triangle ABC is an equilateral triangle , where :- AB = BC = CA = 6 cm .
I don't know what the answer to number 1 is.
2. <u>Center</u>
25x² + 4y² - 50x - 24y - 39 = 0
25x² + 4y² - 50x - 24y = 39
25x² - 50x + 4y² - 24y = 39
25(x² - 2x) + 4(y² - 6y) = 39
25(x² - 2x + 4) + 4(y² - 6y + 9) = 39 + 25(4) + 4(9)
25(x² - 2x + 4) + 4(y² - 6y + 9) = 39 + 100 + 36
25(x² - 2x + 4) + 4(y² - 6y + 9) = 175
<u>25(x - 2)²</u> + <u>4(y - 3)²</u> = <u>175</u>
175 175 175
<u>(x - 2)²</u> + <u>4(y - 3)²</u> = 1

Answer:
<u>options A and D</u>
Step-by-step explanation:
Given x² - 3x - 28
By factor the given function:
x² - 3x - 28 = (x - 7) (x + 4)
So, comparing the results with the given options.
The answer is options A and D
A. X-7
D. X+4
