Answer:

60 ft²

Step-by-step explanation:

ΔABC ≅ ΔDEF

and sides are 8 ft, 15 ft, 17 ft

Area of both triangles will be same as well as any cross section parallel to them and is half the product of legs of right triangle:

A= 1/2*8*15= 60 ft²

See attached for the synthetic division table

The numbers in the bottom row are 1, 9 and 0

The last number is the remainder. So the remainder is 0

The other values in the last row (1 and 9) form the quotient, so we have 1x+9 = x+9 as the final answer

Final Answer: C) x+9

Reil [10]

Answer:

x² - x + 6

Step-by-step explanation:

note (f + g)(x) = f(x) + g(x)

f(x) + g(x)

= x² + 1 + 5 - x ← collect like terms

= x² - x + 6

The solution of the quadratic equation x square - 4 x + 4

zmey [24]

Answer:

$\rm x = 2 , 2$

Step-by-step explanation:

A quadratic equation is given to us and we need to find the solution of the equation. The given equation is ,

$\implies x^2 -4x + 4 = 0$

Now for finding the roots of the equation , let's use the quadratic formula , or by factorising out the equation . Here I would be using the factorization method , as ,

$\implies x^2 -4x + 4 = 0\\\\\implies x^2-2x-2x+4 = 0 \\\\\implies x(x-2) -2(x-2) = 0 \\\\\implies (x-2)(x-2) = 0 \\\\\implies x = 2, 2$

Hence the Solution of the equation is 2,2.

To calculate this percentage, we suggest using this formula:

% / 100 = Part / Total

Substituting the provided values:

60/100 = Part / 20

Performing cross multiplication:

60 x 20 = 100 x Part, or

1200 = 100 x Part

Now just divide by 100 and get the answer:

Part = 1200/100 = 12
