Which equation is true?

amid [387]

Answer:

$(3x-5)(3x+5)$

Step-by-step explanation:

Difference of squares states that:

$a^2-b^2=(a-b)(a+b)$

In this case...

$a^2=9x^2\\\sqrt{a^2}=\sqrt{9x^2}\ (take\ the\ square\ root\ of\ both\ sides)\\a=3x$

$b^2=25\\\sqrt{b^2}=\sqrt{25}\ (take\ the\ square\ root\ of\ both\ sides)\\b=5$

This means that...

$9x^2-25=(3x-5)(3x+5)$

The face of each stone on a walkway was shaped like a trapezoid shown below. 14 inches, 6 inches, 8 inches. What is the area of

marishachu [46]

Answer:

B. 66 square inches

Step-by-step explanation:

Area of a trapezoid = (a + b)/ 2 * h

Where,

a = base a = 14 inches

b = base b = 8 inches

h = height = 6 inches

Area of a trapezoid = (a + b)/ 2 * h

= (14 + 8) / 2 * 6

= 22/2 * 6

= 11 * 6

= 66 inches ²

Area of a trapezoid = 66 inches ²

The correct answer is

B. 66 square inches
