PLS HELP<3ty this is due today! so please helppp tysmmm and have a great night or morning! :) (spam)

so u need to measure it  with a ruler

Step-by-step explanation:

ok so meausre each side

then if all the sides have the same length, then it is a equilateral triangle

if only two of the sides are equal, then it is isoceles

and if all the sides have different lengths, then it is scalene

283 square feet

step-by-step explanation:

good luck

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
