<h2>Hello There today we will solve your problem,</h2>
I will just give your straight forward answers to solve this
- 4(x+3)=52 1. Given
- 4x+12=52 2. Distributive Property
- 4x=40 3. Subtraction Property
- x=10 4. Division Property
S(10) = a + (n-1)d
34 = a + 9d ---- Eqn 1
Sum(20) = n/2(2a +(n-1)d)
710 = 20/2(2a + 19d) ----- Eqn 2
Solve these two equations and find the value of a and d and put the values in the first eqn (a + (n-1)d) to find the 25th term
*n = the term
*a = the starting number
*d = the difference in the series for each number
Answer:
A
Step-by-step explanation:
2x² - 12x - 14
2(x² - 6x - 7)
2(x² - 7x + x - 7)
2(x - 7)(x + 1)
Answer:
The answer is A.
Step-by-step explanation:
(StartFraction d minus b Over c minus a EndFraction) (StartFraction c minus a Over negative d + b EndFraction) = negative 1

Answer:
(d) 8
Step-by-step explanation:
Corresponding sides are proportional.
ED/EG = EC/EF
(6x +3)/17 = (8x -1)/21
21(6x +3) = 17(8x -1)
126x +63 = 136x -17
80 = 10x . . . . . . . . . . . add 17-126x
8 = x . . . . . . . . . . divide by 10
