If you simplify (take out the brackets) of this equation. 5(x+10)=30 then it would be

5 times x + 5 times 10 = 30

5x+10=30

So yes they have the same solution

Write this Trinomial in Factored form 2n^2+15n+7
mariarad [96]

Answer:

(2n+1)(n+7)

Step-by-step explanation:

Here we are given the quadratic expression:

2n^{2}+15n+7

Now we can use AC method to factorise it.

IN this method we first have to multiply 2 and 7.

2 multiplied by 7 equals 14.

Now we have to find two possible factors of 14 which add up to give 15.

Two such possible factors of 14 are 14 and 1.

So now we replace 15n by 14n+1n.

Rewriting the expression,

2n^{2}+14n+1n+7

Factoring by grouping, we have

2n(n+7)+1(n+7)

(2n+1)(n+7)

So the final factored form of the trinomial is

(2n+1)(n+7)

What is 8 6/8 ÷ 2 2/5 = ? (show ur work)
Rama09 [41]

Answer:

175/48

Step-by-step explanation:

Convert 8 6/8 and 2 2/5 to fractions
8 6/8 = 70/8 ; 2 2/5 = 12/5

Now, we have : 70/8 : 12/5
= 70/8 x 5/12
= 70x5/8x12

=350/96
Simplify the fraction, we get 175/48
