2(h+7) simplified. please include how you solved it!

Answers

2 (h + 7) simplified is just using the distributive property where you multiply the coefficient outside the bracket with all the numbers inside the bracket! In this case, we will have to multiply 2 with h and 2 with 7!

2 times h is simply 2h and 2 times 7 is 14

The answer should be 2h + 14

2h +14

7^-3/ 7^5

Answers

Answer:

1/5,764,801

Step-by-step explanation:

We have this as follows

All we have to do is use the laws of indices

We have it that;

a^-x = 1/a^x

a^x/a^y = a^(x-y)

Applying these laws;

7^-3/7^5

= 7^-3-5

= 7^-8

= 1/7^8

= 1/5,764,801

Two vertices of a polygon are (7, −18) and (7, 18) .

What is the length of this side of the polygon?



Enter your answer in the box.

units

Answers

Answer:

36

Step-by-step explanation:

Give the vertices of a polygon as (7, −18) and (7, 18) .

Length of the side is calculated using the formula;

L = √(x2-x1)²+(y2-y1)²

L = √(7-7)²+(18-(-18))²

L = √0+(36)²

L = √(36)²

L = 36

Hence the length of this side of the polygon is 36

If I start with 3 and count by 4's until I reach 99, I get 3, 7, 11, …, 99, where 3 is the first number, 7 is the second number, 11 is the third number, and so on. If 99 is the Nthnumber, what is the value of N?

Answers

Answer:

Given variables:

a=3

d=4

Tn=99

N=?

Using the formula

Tn=a+(n-1)d

99=3+(n-1)4

96=4(n-1)

24=n-1

25=n

Therefore N=25

work out the equation of the line which has a gradient of 2 and passes through the point (1,4).

Answers

Answer:

y = 2x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (1, 4) into the partial equation

4 = 2 + c ⇒ c = 4 - 2 = 2

y = 2x + 2 ← equation of line

Answer: y=2x+2
