h = 45 inches
Dominics son is 45inches tall
513 as a percentage of 900 can be re-written as;

= 57 percent
Solution:
2(6+7)= 3(5+2)
Step ; 1 { Solving first Term i.e LHS }
LHS : 2 ( 6 + 7)
☞ 2 ( 13)
☞ 2 × 13
☞ 26
Now, RHS ; 3 ( 5 + 2)
☞ 3 ( 7)
☞ 21
From Equation 1 and 2, We can LHS and RHS are not Equal.
Therefore, 26≠ 21.
(3x-4)(3x-4) is the answer because when something is squared, it's just multiplying itself by itself, this also applies to expressions.
