Esmeralda I think it's wrong cuz it’s like the question but that's added a parentheses so I think that's wrong
2x + 5 =7
Subtracting 5 from both sides
= 2x +5-5 = 7-5
=2x = 2
= x = 2/2
=x = 1
This an isosceles right triangle. The sides opposed to the angle 45° are congruent. Let x be this side==> x²+x² =(7√2)² (Pythagoras)
2x² = 49(2) ==> 2x²= 98 ==> x²=49 & x=7
<span>Hey there, Lets solve this step by step.
</span>
<span>"Two times the quantity of a number minus 12”
</span><span>Two times the quantity = 2 * n
</span>
<span>number minus 12 = n - 12
</span>
Therefore
2n-12
