Solve the equation. 5x + 8 - 3x = -10 x = -9 (0) x = -1 C X = 1 x = 9

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
