Find the area of each figure below

Ugo [173]

Answer:

25. $27a^{3}b^{2}$

26. $3\pi x^{3}y$

Step-by-step explanation:

For 25:

$A = \frac{a+b}{2} h$ (area of a trapezoid)

$A=\frac{11a^{2}b+7a^{2}b}{2} *3ab$ (substitute terms)

$= \frac{18a^{2}b}{2}*3ab$ (collect like terms)

$= 9a^{2}b*3ab$ (reduce the fraction by crossing out 2)

$= 27a^{3}b^{2}$ (calculate)

For 26:

$A=\pi r^{2}$ (equation of area of a circle)

$A=\pi (3x^{3} y)^{2}$ (enter the radius)

$= 3\pi x^{3} y$ (communtative property to reorder the terms)

If x=4 is a root, what is the corresponding factor?

Airida [17]

Answer:

(x - 4)

Step-by-step explanation:

Given x = a is a root then (x - a) is the corresponding factor

Given x = 4 is a root, then

(x - 4) ← is the corresponding factor

Note if x = - 4 is a root , then

(x - (- 4)), that is (x + 4) is the corresponding factor
