The length of a rectangle is 4 yd more than twice the width x. The area is 390

masya89 [10]

Step-by-step explanation:

step 1. let l be the length of the rectangle

step 2. l = 2x + 4

step 3. lx = 390 yd^2

step 4. (2x + 4)x = 390

step 5. 2x^2 +4x = 390

step 6. 2x^2 + 4x - 390 = 0

step 7. -4 +- sqr(4^2 -4(2)(-390))/2(2) quadratic formula

step 8. (-4 +- sqr(3136))/4

step 9. (-4 +- 56)/4

step 10. x = 13yd, l = 2x + 4 = 2(13) + 4 = 30yd.

A baseball team played 154 regular season games. The ratio of the number of games they won to the number of games they lost was

ELEN [110]

Answer:

Number of games won = 110

Step-by-step explanation:

Given:

Total games played = 154

The ratio of number of games won to number of games lost = $\frac{5}{2}$

Solution:

Let the number of games won be = $5x$

Thus, number of games lost = $2x$

The total games played can be given as = $5x+2x=7x$

Thus, we have:

$7x=154$

Dividing both sides by 7.

$\frac{7x}{7}=\frac{154}{7}$

∴ $x=22$

So, number of games won = $5\times 22 = 110$
