You would bring the division over to to other side. When we switch it to the other side, it turns into a multiplication (the opposite of division). So we go from:
102 / 3 = 34
to
102 = 34 * 3
Which is C for your multiple choice! :)
X-2=10
or
10=x-2
this is because it says "2 less than a number is 10" so we can infer that 2 is less than a number (x) so knowing that less than means subtract x-2=10 or you can put it as 10=x-2
X^3 + 7*x^2 + -16*x-112
=(x + 4)*(x + 7)*(x - 4)
Answer:
8x^2 + 5y + 1
Step-by-step explanation:
1 + x^2 - 3 + 2y + 7x^2 + 3 + 3y
group like terms
= x^2 + 7x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 2y + 3y + 1 - 3 + 3
add similar items
= 8x^2 + 5y + 1 - 3 + 3
= 8x^2 + 5y + 1
