Answer:

b. 106 sq.cm

Step-by-step explanation:

A=L×W

A1= 2(5×8) = 2(40) = 80

A2= 2(1×8) = 2(8) = 16

A3= 2(5×1) = 2(5) = 10

Total area = 80 + 16 +10 = 106 sq. cm

How do you find "a" in -10+a=6a-7a please help I do not know how to find what the answer is.

Sunny_sXe [5.5K]

-10 + a = 6a - 7a

Rearrange the left hand side

a - 10 = 6a - 7a

Simplify 6a - 7a

a - 10 = -a

Add a on both sides

2a - 10 = 0

Add 10 on both sides

2a = 10

Divide by 2 on both sides

a = 5

Ac method for x^2+20x-8=0

yanalaym [24]

<h2>Explanation:</h2><h2></h2>

By using quadratic formula:

$x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$\quad a=1,\:b=20,\:c=-8$

$x_{1,\:2}=\frac{-20\pm \sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}$

$x=\frac{-20+\sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}:\quad 2\left(3\sqrt{3}-5\right)$

$x=\frac{-20-\sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}:\quad -2\left(5+3\sqrt{3}\right)$

So the solutions are:

$\boxed{x=2\left(3\sqrt{3}-5\right),\:x=-2\left(5+3\sqrt{3}\right)}$
