Find the area of the trapezoid with a base of 19 inches, height 12.6 inches and base 29.2 inches

kati45 [8]

A trapezoid is a quadrilateral with two parallel sides of different lengths. This means that any of the two sides can be called a base, and that the trapezoid is unique because it has two bases.
the formula for finding the area of a trapezoid is
[(b1 + b2) x h] / 2
Substituting the values:
((19 + 29.2) * (12.6)) / 2
303.66 in ^ 2
Answer:
the area of the trapezoid is:
303.66 in ^ 2

Solve the radical equation. square root 6n-11= n – 3 Which solution is extraneous? A.)2

Anvisha [2.4K]

ANSWER

D) 10

EXPLANATION

We want to solve the radical equation,

$\sqrt{6n - 11} = n - 3$

Square both sides,

$6n - 11 = (n - 3) ^{2}$

Expand brackets on right hand side,

$6n - 11 = {n}^{2} - 6n + 9$

Rewrite in general quadratic equation form,

${n}^{2} - 12n + 20 = 0$

Factor to obtain,

$(n - 2)(n - 10) = 0$

Apply the zero product principle to get,

$n = 2 \: or \: n = 10$

We put n=2 into the equation to get,

$\sqrt{6(2) - 11} = 2 - 3$

$1 = - 1$

This statement is false, hence 2 is an extraneous solution

We put n=10, to get

$\sqrt{6(10) - 11} = 10 - 3$

$\sqrt{49} = 7$

$7 = 7$

This is true, hence the only solution is
$n = 10$
