Answer:

(p-2l)/2 = b

Step-by-step explanation:

Formula for perimeter of a rectangle = 2(l + b)

We know,

perimeter = 80

length = 12

if we substitute the values -

p = 2 ( l + b )

p = 2l + 2b

(p-2l)/2 = b

(if you need the width : b = (p-2l)/2 = 80-24/2 = 56/2 = 28cm)

Answer:

$x_{1} =-14\\\\x_{2} =6$

Step-by-step explanation:

$x^{2} +8x-84=0\\\\x=\dfrac{-b \pm \sqrt{b^{2}-4ac } }{2a} \\\\a=1; \: \: b=8; \: \: c=-84\\\\x=\dfrac{-8 \pm \sqrt{8^{2}-4 \cdot 1 \cdot (-84) } }{2 \cdot 1}=\dfrac{-8 \pm \sqrt{400 } }{2}=\dfrac{-8 \pm20}{2} =-4 \pm 10\\\\x_{1} =-14\\\\x_{2} =6$

Find the missing side of the triangle

Katena32 [7]

$\\ \sf\longmapsto sin\theta=\dfrac{Perpendicular}{Hypotenuse}$

$\\ \sf\longmapsto sin74=\dfrac{n}{40}$

$\\ \sf\longmapsto n=40sin74$

$\\ \sf\longmapsto n=35(0.96)$

$\\ \sf\longmapsto n=38.4$

3y-15-6x in slope intercept form

ASHA 777 [7]

When you think of slope intercept form we think of Y=mx+b
m=slope and b = intercept

So all you do is solve for Y in your given equation.

Im going to guess the equal sign because you didn't include it. I can fix the answer is I was wrong.

3y-15=6x (add 15 to both sides)

3y=6x+15 (divide by 3)

y=2x+3 (final answer)
