The two numbers are 22 and 7.
22 + 7 = 29
22 - 7 = 15
here is how we can find these numbers;
let a and b are two numbers
a + b = 29
a - b = 15
a = 15 + b
now put this value of a in any of the equation
a + b = 29
15 + b + b = 29
15 + 2b = 29
2b = 29 - 15
2b = 14
b = 7
now put the value of b to find the value of a;
a = 15 + b = 15 + 7 = 22
a = 22
Answer:
The correct answer is 6 jars can be used
Step-by-step explanation:
According to the given scenario, the calculation of the number of jars needed is shown below:
The 1 1 ÷ 2 liters means = 3 ÷ 2 liters
And, the paint is divided into 1 ÷4 liter jars
So, the number of jars needed is
= (3 ÷ 2) ÷ ( 1 ÷ 4)
= (4 × 3) ÷ 2
= 6 jars needed
Therefore the number of jars needed is 6 jars
Answer: I'm sorry but you'd have to be more specific. Please include numbers.
Step-by-step explanation:
There are four rectangles and 2 squares.
Let’s start with the four rectangles.
4 [ 2x(x)]
4 [ (2*7)(7)] = 392 cm^2
______________
Next, let’s find the SA for the two squares.
2 [(2x)^2]
** I need to be clear that both the 2 and the x in the parentheses are squared because the square, of course, is a “perfect square”. This was probably obvious and needless to say, haha oh well.
Next step: plug in values
2 [ [2(7)]^2 ] = 392 cm^2
TOTAL: 392+392 = 784 cm^2
Wow I should have realized the the 4 rectangles are the area as the two squares.
Good luck to you!

Answer:
c = 34
Step-by-step explanation:
x²+19x+c=0
(x + a) (x + b) = x² + (a + b) x + ab
a + b = 19
a - b = 15
a = 17
b = 2
c = ab = 34
