Find the area of the figure. Use 3.14 for π.

196.48m²

Step-by-step explanation:

AREA OF THE PICTURE = AREA OF TRIANGLE + AREA OF SEMI CIRCLE

Length of base of the triangle = 16m

Length of perpendicular height of triangle = 12m

Area of triangle =

Length of diameter of semi-circle = 16m

Length of radius of semi-circle =

Area of semi circle =

AREA OF THE FIGURE = 100.48 + 96 = 196.48m²

your answer would be 12

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
