Answer 1

Answer:

x = [tex]\sqrt{66}[/tex]

Step-by-step explanation:

This is using the altitude on hypotenuse theorem

(leg of big Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )

x² = 6 × (6 + 5) = 6 × 11 = 66 ( take square root of both sides )

x = [tex]\sqrt{66}[/tex]

Answer:

2x + 5y = 7

Step-by-step explanation:

Here, 2x = 7 - 5y is given

The Standard form of equation is

Ax + By = C

Here, Ax = 2x; By = -5y; C = 7

Now, we get

2x = 7 - 5y

2x + 5y = 7

Here we get Ax = 2x; By = 5y; C = 7

Thus, The Standard form of equation is

2x + 5y = 7

Determine two numbers that have a product of 40 but have a sum of 13.

Answers

Answer:

The two numbers are 8 and 5.

Step-by-step explanation:

Let consider x and y to be these two numbers.

So;

(x) * (y) = 40 ---- (1)

x + y     = 13 ----- (2)

From (2), let x =  13 - y

Then;

(13 - y) * y = 40

13y - y² = 40

13y - y² - 40 = 0

-y² + 13y - 40 = 0

Multiply through by (-)

y² - 13y + 40 = 0

By factorization;

(y - 8) (y - 5) = 0

y = 8 or  y = 5

CHECK:

8 * 5 = 40

8 + 5 = 13

Therefore, the two numbers are 8 and 5.
