Answer:
A) 288.62
Step-by-step explanation:
10.4×15.3= 159.12
10.4²+15.3²= X²
342.25= X²
18.5= X
7×18.5= 129.5
129.5+159.12= 288.62
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
That's answer.
