which qaudratic equation is equivalent to (x+2)^2+5(x+2)-6=0 a. (u+2)^2+5(u+2)-6=0 where u=(x-2) b. u^2+4+5u-6=0 where u= (x-2)

Lisa [10]

Answer:

Step-by-step explanation:

Given

(x + 2)² + 5(x + 2) - 6 = 0

Using the substitution u = x + 2 , then the equation can be expressed as

u² + 5u - 6 = 0 → D

Runners in the half marathon entered in three waves. There were 341 runners in the first wave, 295 runners in the second wave, a

Natasha_Volkova [10]

190 runners would not have finished the race.

If you add up all the waves, there were 952 total runners.

If 7/8 finished the race, then that means that 1/8 did not finish the race.

Just multiply 1/8 by 952 to get the amount that did not finish.
It would be 190.

(a) Work out the reciprocal of 1.25

Oxana [17]

Answer:

0.8 OR $\frac{4}{5}$

Step-by-step explanation:

The reciprocal of any number is the number that it multiplies by to equal 1.

The reciprocal can be found by simply converting the number into a fraction and then 'flipping' the fraction as any number multiplied by its reciprocal is 1.

E.g.

No. X/Y * Y/X (its reciprocal) = 1

$\frac{x}{y} *\frac{y}{x} =\frac{xy}{xy} =1$
