Answer:
x^2 + 18x + 76 + 5 = 0 + 5
Step-by-step explanation:
The first step is to determine the constant that is needed to be able to write the expression in the desired form. That constant is the square of half the x-term coefficient: (18/2)^2 = 9^2 = 81.
The constant that is present is 76, which is 5 fewer than the needed constant, so the "first step" is to add 5 to both sides of the equation:
x^2 + 18x + 76 + 5 = 0 + 5
Then the next step would be to write the left side as a square:
(x +9)^2 = 5 . . . . . . . p = -9; q= 5
Answer:
Step-by-step explanation:
soulution:
given, 2x +2x = 16 <em>-</em> <em>2x</em> + 3y = 14
2x <em>+ 2x</em> = <em>-2y </em>+3y = 14 -16
4x = y = -2
y = 4x = -2
y = x = 4/-2
x = y = <u><em>-2 ans</em></u>
The only possibility if a number is not even is that it is odd. Thus, the event would be the product is an odd number.

for the 3 single digit number that will be multiplied together to get the
product 504.
=> n x n x n = 504 – where n are the single digits that we need to multiply.
504 / 2 = 252
504 / 3 = 168
504 / 4 = 126
504 / 5 = 100.8
504 / 6 = 84
504 / 7 = 72
504 / 8 =63
504 / 9 = 56
Now, let’s have 7 8 9 as 3 numbers to multiply to get 504 as product.
=> 7 x 8 x 9
=> 504

Step-by-step explanation:
Mass (m) = 11 g
volume (v) = 13 ml
density (d) = ?
We know density is defined as mass per unit volume so
d = m / v
= 11 / 13
= 0.85 g/ml
Density (d) = 0.85 g/ml
