Answer:
x = 4
Step-by-step explanation:
Since the terms are in an arithmetic progression then there is a common difference between consecutive terms, that is
2x - 1 - (x + 1) = x + 5 - (2x - 1) ← distribute parenthesis on both sides
2x - 1 - x - 1 = x + 5 - 2x + 1, that is
x - 2 = - x + 6 ( add x to both sides )
2x - 2 = 6 ( add 2 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
The 3 terms are 5, 7, 9
Answer:
82m²
Step-by-step explanation:
split it into a rectangle and square
3x6=18
8x8=64
total area = 82
Answer:
98.
Step-by-step explanation:
You have to do it in order so you can get the correct answer. Do the problem in the parenthesis first. 6 ÷ 3 = 2.
It should look like this:
7² x 2.
Then, do your exponents. 7² is just basically 7 x 7. It equals 49.
Now, it should look like this:
49 x 2. Multiply 49 x 2, and your answer should be 98.

At the point/angle E:
- the adjacent side(side <u>next to</u> the point/angle) is ED
- the opposite side(side of the triangle <u>across</u> from the point/angle) is DF
- the hypotenuse (the<u> longest side</u> of the triangle) is EF.

Answer: h(-4)
Step-by-step explanation:
If h(x) something is equal to 4 then set the equation equal 4 and solve for t.
4t +20 = 4
-20 -20
4t = -16
t = -4
So h(-4) = 4
