Answer:
285, 7392, 15708, are divisible by 3 but not by 9
Step-by-step explanation:
it's because of we add the sun of the digits, 285, 7392, 15708, they are divisible by 3. actually, except for 629, all of them are divisible by 3, but 5490 and 43695 are both divisible by 3 and 9
9 because it take 3 to fill 1/3 do 3 times 3 and its nine
X is the number
<span>The sum of two numbers is 11, so other number is : 11 - x
</span><span>The sum of their squares is 65
</span>
x^2 + (11 - x)^2 = 65
x^2 + 121 - 2(x)(11) + x^2 = 65
2x^2 - 22x + 121 = 65
2x^2 - 22x + 121 - 65 = 0
2x^2 - 22x + 56 = 0
2(x^2 - 11x + 28) = 0
2(x - 7)(x -4 ) = 0
x - 7 = 0
x = 7
x - 4 =0
x =4
answer: the numbers are 4 and 7
double check:
<span>sum of two numbers is 11:
4 + 7 = 11
</span><span>The sum of their squares is 65
</span><span>4^2 + 17^2 = 16 + 49 = 65

Question
Which of the following equations is equivalent to 5(2p-6)=40?
Let's solve your equation step-by-step.
5(2p−6)=40
Step 1: Simplify both sides of the equation.
5(2p−6)=40
(5)(2p)+(5)(−6)=40(Distribute)
10p+−30=40
10p−30=40
Step 2: Add 30 to both sides.
10p−30+30=40+30
10p=70
Step 3: Divide both sides by 10.
10p/10=70/10
p=7
ANSWER =
The answer is A. because...
10p−30=40 = p=7
ANSWER = A.
hope i helped have a wonderful day..can i get a brainliest please and thank you...
