First, we translate the information that the question gives us:20+x is "twenty added to a certain number"(20+x)/5 is "the sum divided by five"1+12x is "one more than twelve times the original number"Putting it all together, we get the following equation:(x+20)/5 = 1 + 12xSolve for x:x+20=5(1+12x)x+20=5+60x20-5=60x-x15=59x15/59 = xTherefore, the original number was 15/59
1) (-5)(-3) is 15
2) 24/-4 is -6
3) 36(0.5) is 18
The first one would be 1 dash after the last one. The second one would be in the middle of the 3rd and 4th dash, the 3rd would b at 2. The fourth would b slightly after the 1st dash after 3. And the last would be in the middle of the 1st dash after 2.5 and the 2nd
Answer:
B
Step-by-step explanation:
Substitute x = h + 2 into f(x), that is
f(h + 2)
= 4(h + 2)² - 17 ← expand factor using FOIL
= 4(h² + 4h + 4) - 17 ← distribute parenthesis and simplify
= 4h² + 16h + 16 - 17
= 4h² + 16h - 1 → B
Step-by-step explanation:
½× 10 × 5√3 cm² =
