2y - 3 = 4y + 6
Subtract 6 from both sides
2y -9 = 4y
Subtract 2y from both sides
-9 = 2y
Divide both sides by 2

Two side of a triangle are 26 and 27, while the height to the third side is 25. Find the area of the triangle.
Based on the information given, the area of the triangle is 291.85.
From the information given,
A = 26
A = 26B = 27
A = 26B = 27C = 25
Firstly, we'll add the sides given and divide them by 2. This will be:
S = (26 + 27 + 25) / 2
S = 78/2
S = 39
Then we will use the formula:
= s(s - a)(s - b)(s - c)
= 39(39 - 26)(39 - 27)(39 - 25)
= 39(13 × 12 × 14)
= 85176
Lastly, we'll find the square root of the value gotten. This will be:
= ✓85176
= 291.85.
Therefore, the area is 291.85.

Step-by-step explanation:
The sum to n terms of a geometric sequence is
[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex]
where a is the first term and r the common ratio
Here a = 2 and r = a₂ ÷ a₁ = 9 ÷ 3 = 3 , then

please tell me what is -9d×2-d×2
Answer:
I believe it's (2d - 1) • (d + 2)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is 3 .
-4 + 1 = -3
-2 + 2 = 0
-1 + 4 = 3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and 4
2d2 - 1d + 4d - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
d • (2d-1)
Add up the last 2 terms, pulling out common factors :
2 • (2d-1)
Step-5 : Add up the four terms of step 4 :
(d+2) • (2d-1)
Which is the desired factorization

Evaluate the following by writing it as a difference of two squares first:
103^2 − 97^2
Answer:
1200
Step-by-step explanation:
A difference of 2 squares factors in general as
a² - b² = (a - b)(a + b) , then
103² - 97²
= (103 - 97)(103 + 97)
= 6 × 200
= 1200
The correct answer is 1200.
What is the difference between two squares called?Where one perfect square is subtracted from another, is called a difference of two squares. It arises when (a − b) and (a + b) are multiplied together. This is one example of what is called a special product.
A difference of 2 squares factors in general is written as
a² - b² = (a - b)(a + b) , then
