Answer:15504

Step-by-step explanation:

We know to select any r no of non-consecutive element for n consecutive elements is given by

$^{n-k+1}C_k i.e. \left ( ^{n-k+1}_k \right )$

Here n=24 and r=5

Therefore no of ways $=^{24-5+1}C_5$

$=^{20}C_5$

$=\frac{20!}{15!5!}$

$=15504$

The figure shows a triangle with 2 congruent sides. The angle between the congruent sides measures x degrees and a different ang

Mandarinka [93]

Answer:

40°

Step-by-step explanation:

Since the triangle is isosceles and the angle between the congruent sides is x, the other two angles measure the same value.

Sum of the interior angles is 180°:

x + 2*70° = 180°
x + 140° = 180°
x = 40°

Solve a-5/a+4 = 5/4 a=0 a=-1 a=-9 a=-40

umka21 [38]

Answer:

Step-by-step explanation:

we have

$a- \frac{5}{a} + 4 = \frac{5}{4}$

we multiple both sides by (4a)

$4a^{2} -20+ 16a= 5a\\4a^{2} + 11a - 20=0$

The delta = 11^2 - 4*4*(-20)= 121 + 320= 441= 21^2

These 2 solutions are:

$x_{1}=\frac{-11+ 21}{4*2} =\frac{10}{8} =\frac{5}{4} \\x_{2}=\frac{-11 - 21}{4*2} =\frac{- 32}{8} = - 4$

Solution: - 4 , 5/4

But maybe you wrote:

$\frac{a-5}{a+4}=\frac{5}{4} \\ 4(a-5)=5(a+4)\\4a -20= 5a+ 20\\4a-5a= 20 + 20\\-a = 40\\or\\ a= -40\\$

So a = -40

P.S: Pay attention to using parentheses
