17g+6=20g+3 Solve for the variable g.

Answers

1g is the answer

minus 6 and 3=3
minus 17 and 20
3g=g
1=g

You need to isolate the variable g onto one side. Since we're going backwards, we need to do the opposite of the order of operations. Step one is to subtract 20g from both sides. 17g-20g is -3g. -3g+6=3. Now, subtract 6. 3-6=-3.
-3g=-3. Finally, divide both sides by -3. -3/-3 is 1, so G is 1.

Answers

By translating triangle ABC 4 units up and 3 units left to form triangle A'B'C' means that the line joining each of the corresponding points represents the hypothenus of a right triangle with legs 4 units and 3 unit. To find the length of each corresponding points, we use the prthagoras theorem which states that the square of the length of the pythagoras of a right triangle is equal to the sum of the squares of the lenght of other legs. i.e. the square of the required distance = 4^2 + 3^2 = 16 + 9 = 25 Therefore, the distance of eachcorresponding side is given by the square root of 25 = 5.

Which trinomials are perfect square trinomials?Choose exactly two answers that are correct.

a2 + 4a + 16

a2 + 14a + 49

a2 + 15a + 75

a2 + 26a + 169

Answers

The exactly two answers are correct are a² + 14a + 49 and a² + 26a + 169.

What are trinomials?

The condition for the perfect trinomials is if the coefficient of a² = 1 and If you divide the middle number coefficient by 2 and you square it you get the last term.

For all the options, the coefficient of a² = 1.

a² + 4a + 16.

Coefficient of a = 4.

4/2 = 2

2² = 4, this does not equal the last term so it is not a perfect square trinomial.

a² + 14a + 49.

Coefficient of a = 14.

14/2 = 7

7² = 49, this is equal to the last term so it is a perfect square trinomial.

And the perfect square is (a +7)²

Similarly, if you test the last option.

a² + 26a + 169.

Coefficient of a = 26.

26/2 = 13

13² = 169, this is equal to the last term so it is a perfect square trinomial.

And the perfect square is (a +13)²

The only two options are: a² + 14a + 49 and a² + 26a + 169. Other options do not pass this test.

You can know a perfect square trinomial:

i) if the coefficient of a² = 1.

ii) If you divide the middle number coefficient by 2 and you square it you get the last term.

Take for example the first option:

For all the options, the coefficient of a² = 1

a² + 4a + 16.

Coefficient of a = 4.
4/2 = 2
2² = 4, this does not equal the last term so it is not a perfect square trinomial.

a² + 14a + 49.

Coefficient of a = 14.
14/2 = 7
7² = 49, this is equal the last term so it is a perfect square trinomial.
And the perfect square is (a +7)²

Similarly if you test the last option.

a² + 26a + 169.

Coefficient of a = 26.
26/2 = 13
13² = 169, this is equal the last term so it is a perfect square trinomial.
And the perfect square is (a +13)²

So the only two options are: a² + 14a + 49 and a² + 26a + 169.

Other options do not pass this test.
