X² <span>− 3x − 70=0
</span>x² + 7x - 10x − 70=0
x(x+7) - 10(x+7) = 0
(x+7)(x-10) = 0
x + 7 = 0 or x - 10 = 0
x = -7 x = 10
Answer: x=-7, x=10
Answer:
<h2><u><em>
46 cm²</em></u></h2>
Step-by-step explanation
the figure is composed of a square with an isosceles right triangle inside, we find the area of the square and we take away the area of the triangle.
Triangle area = lxl, right-angled triangle area side by side divided by two.
8 * 8 = 64cm²
6 * 6 : 2 = 18 cm²
Area of the shaded region
64 - 18 = 46 cm²
Answer:
Step-by-step explanation:
Considering the equation
Solving
As
![=\left(x+1\right)\frac{x^4+8x^3+8x^2+8x+7}{x+1}...[A]](https://tex.z-dn.net/?f=%3D%5Cleft%28x%2B1%5Cright%29%5Cfrac%7Bx%5E4%2B8x%5E3%2B8x%5E2%2B8x%2B7%7D%7Bx%2B1%7D...%5BA%5D)
Solving
Putting = 
in equation [A]
So,
![\left(x+1\right)\frac{x^4+8x^3+8x^2+8x+7}{x+1}...[A]](https://tex.z-dn.net/?f=%5Cleft%28x%2B1%5Cright%29%5Cfrac%7Bx%5E4%2B8x%5E3%2B8x%5E2%2B8x%2B7%7D%7Bx%2B1%7D...%5BA%5D)
As
So,
Equation [A] becomes
So, the polynomial equation becomes

<h3>
It is equivalent to 2a+2b</h3>
We use the distributive property.
Multiply the outer term 2 by each term inside ('a' and b)
2 times a = 2a
2 times b = 2b
We add those results to get 2a+2b. We cannot combine these terms as they are not like terms.
If the diameter is 30 ft then the area of the circle is 706.5 you can approximate it if you want and you will have 707.
