Answer:
infinitely many solutions
Step-by-step explanation:
1) distribute 9 to each term inside parenthesis on left side of equation
18x+90=2(9x+45)
2)now distribute 2
18x+90=18x+90
these equations are exactly the same! this means that this equation has infinitely many solutions
Hope this helps!
Answer:
7x^2 + 7
Step-by-step explanation:
So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.
Hope that explanation makes sense
The numbers 5, 12 and 13 can be used to correctly identify the sides of a right triangle, and this can be proven by using the Pythagorean Theorem.
5² + 12² = 13²
25 + 144 = 169
169 = 169
5 and 12 are the legs, and 13 is the hypotenuse. Hopefully this is what the question is asking. :)
