Let x be the number multiplied by 7.
We get 7x.
At least 30 means GREATER THAN OR EQUAL TO 30 or ⩾ 30.
Put it all together now.
7x ⩾ 30
Divide both sides by 7.
x ⩾ 30/7
Done!
Yes. Because 7,24,25 are sides of right triangle so if we multiply sides by 2, the new triangle would be congruent with the 1st one. So it's right too...
The answer is A because completing the square gives a minimum of 2,-9 and factorising gives roots of 5 and -1 :)
