The value of m is 3.

Solution:

Given equation:

6 + 5(m + 1) = 26

<u>To solve the equation:</u>

6 + 5(m + 1) = 26

Multiply 5 into each term inside the bracket.

6 + 5m + 5 = 26

5m + 11 = 26

Subtract 11 on both sides, we get

5m = 15

Divide by 5 on both sides, we get

m = 3

The value of m is 3.

Checking:

6 + 5(m + 1) = 6 + 5(3 + 1)

                    = 6 + 5(4)

                    = 6 + 20

                    = 26

6 + 5(m + 1) = 26.

Hence the solution is correct.

What is the 72nd term of -27, -11, 5
FinnZ [79.3K]

Answer:

1109

Step-by-step explanation:

The first term is -27, and the common difference is 16.

The nth term is:

a = a₁ + d (n − 1)

a = -27 + 16 (n − 1)

a = -27 + 16n − 16

a = 16n − 43

The 72nd term is:

a = 16(72) − 43

a = 1109

Factor 75t2 + 12.<br> 3(5t + 2)2<br> 3(25+2 +4)<br> 3(251-4)
frosja888 [35]

Answer:

75t^2+12=3(25t^2+4)

Option C)

Step-by-step explanation:

Here we are given with the expression 75t^2+12

The GCF of 75t^2 and 12 is 3

Hence we take 3 as GCF and bring it in front of the bracket.

3(25t^2+4)

It can not be factorise furthure  as there is no GCF of 25 and  also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

3(25t^2+4)

Option C)

Find the measure of angle x in the figure below:
BartSMP [9]
First, it's worth noting that angles on a straight line sum to 180°. We can use this information to find out the value of y:
180-52-59=69
y=69°
Another rule is that the angles in a triangle sum to 180° as well. This means that we can now find out x:
63+y+x=180
63+69+x=180
180-63-69=x
x=48°
