1 answer:
Free_Kalibri [48]4 years ago

Answer:

(5, 4 )

Step-by-step explanation:

Given the 2 equations

4x + 6y = 44 → (1)

4x + 2y = 28 → (2)

Subtracting (2) from (1) term by term eliminates the term in x, that is

(4x - 4x) + (6y - 2y) = (44 - 28), that is

4y = 16 ( divide both sides by 4 )

y = 4

Substitute y = 4 into either of the 2 equations and solve for x

Substituting y = 4 in (1)

4x + 6(4) = 44

4x + 24 = 44 ( subtract 24 from both sides )

4x = 20 ( divide both sides by 4 )

x = 5

Solution is (5, 4 )

Doss [256]

Answer:

64

Step-by-step explanation:

height of the hypotenuse:

\sqrt{60^2-36^2} = \sqrt{3600 - 1296} = \sqrt{2304} = 48

36 : height = height : x

36 : 48 = 48 : x

x= 48^2/36 = 64

Factor 4x 2 + 12x + 5 . (2x + 5)(2x + 1)
Juliette [100K]
Factor
in form
ax²+bx+c form
use the ac method
1. mulitply a and c
2. factor the result such that the 2 factors add to b
3. split b into those 2 factors
4. group the terms
5. undistribute common factors
6. undistribute again





first multiply ac
4 times 5=20
now
what 2 numbers multiply to 20 and add to 12
2 and 10
4x²+2x+10x+5
group
(4x²+2x)+(10x+5)
undistribute
2x(2x+1)+5(2x+1)
undistribute the (2x+1)
(2x+1)(2x+5) is factored form whih you have there, nice
