Jenny has 3 times as many new toys as favorite toys. favorite toys is x in this equation. so 3x new toys as x favorite toys. 4x. if she also has old toys then she has 10 favorite toys. i believe this is the answer.
2x1+(1+7)+(7x2)➡️ 3+(8)+(14)➡️25
Answer:
38 inches
Step-by-step explanation:
just add them all together.
Hello,
2(x²+5)=60
<==>x²+5=30 (divided teh 2 members by the positive 5 :keep the equality)
<==>x²-25=0 (substract 25 from 2 members)
<==>(x-5)(x+5)=0 (remarquable product a²-b²=(a+b)(a-b))
<==> x= 5 or x=-5 (a product if null if one at least of its factor is null)
The answers are that the number can equal -4 or 1.
You can find this by setting the number equal to x.
x^2 (The square of a number) + 3x (three times a number) = 4
x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0
Then you can factor this to find the answers
(x - 4)(x + 1) = 0
Set both equal to 0 and solve.
