Solve for y 16y^2-25=0

Pepsi [2]

Answer:

$\large\boxed{x=-\dfrac{5}{4}\ \vee\ x=\dfrac{5}{4}}$

Step-by-step explanation:

$16y^2-25=0\\\\METHOD\ 1:\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\16=4^2\ \text{and}\ 25=5^2\ \text{therefore we have}\\\\4^2y^2-5^2=0\\\\(4y)^2-5^2=0\\\\(4y-5)(4y+5)+0\iff4y-5=0\ \vee\ 4y+5=0\\\\4y-5=0\qquad\text{add 5 to both sides}\\4y=5\qquad\text{divide both sides by 4}\\\boxed{y=\dfrac{5}{4}}\\\\4y+5=0\qquad\text{subtract 5 from both sides}\\4y=-5\qquad\text{divide both sides by 4}\\\boxed{x=-\dfrac{5}{4}}$

$METHOD\ 2:\\\\16y^2-25=0\qquad\text{add 25 to both sides}\\\\16y^2=25\qquad\text{divide both sides by 16}\\\\y^2=\dfrac{25}{16}\to y=\pm\sqrt{\dfrac{25}{26}}\\\\y=-\dfrac{\sqrt{25}}{\sqrt{16}}\ \vee\ x=\dfrac{\sqrt{25}}{\sqrt{16}}\\\\\boxed{y=-\dfrac{5}{4}\ \vee\ x=\dfrac{5}{4}}$

There are 3 consecutive integers that add up to 9 which integers are they?

matrenka [14]

Answer:

The integers are 2,3,4

Step-by-step explanation:

Let one integer be = $x$

Since, the integers are consecutive, so they will increase by one.

So, 2nd integer will be = $x+1$

3rd integer will be = $x+1+1=x+2$

It is given that the 3 integers add up to 9.

So, we have the sum equation as:

$x+x+1+x+2=9$

Solving for $x$

Combining like terms.

$3x+3=9$

Subtracting both sides by 3.

$3x+3-3=9-3$

$3x=6$

Dividing both sides by 3.

$\frac{3x}{3}=\frac{6}{3}$

$x=2$

∴ 1st integer = $2$

2nd integer = $2+1 = 3$

3rd integer = $2+2 = 4$

Plz help and show work. If you show work I will make you brainiest.

topjm [15]

I believe it would be 71 degrees because the total degrees of a triangle is 180 so 57+52=109 then 180-109=71 which would then be the final angle degree.
Hope I helped
