0.35%

Step-by-step explanation:

T = 18 months = 1.5 years

SI = P × R × T

26.25 = 500 × R/100 × 1.5

R = 26.25 × 100 / (500 × 15) = 5.25/15 = 0.35 % annually

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

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.
