Answer:
The answer is below
Step-by-step explanation:
Let us assume that the age of Greg's brother (Gabe) is x years, and let Greg's age by y years. Since Greg is 10 years older than his brother gabe, then:
y = x + 10 (1)
Also. Greg is 3 times as old as Gabe, hence:
y = 3x (2)
From equation 1 and equation 2:
y = x + 10 = 3x
Hence:
3x = x + 10
Subtracting x from both sides gives:
3x - x = x + 10 - x
2x = 10
Dividing by 2:
2x/2 = 10/2
x = 5 years
y = x + 10 = 5 + 10 = 15 years
Therefore Gabe is 5 years old and Greg is 15 years old
The common difference is (1,0.38).
An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same. In this type of progression, there is a possibility to derive a formula for the nth term of the AP. For example, the sequence 2, 6, 10, 14, … is an arithmetic progression (AP) because it follows a pattern where each number is obtained by adding 4 to the previous term.
x1 = 1 , y1 = 24
x2 = 2, y2 = 24.38
x3 = 3 , y3 = 24.76
x4 = 4 , y4 = 25.14
Thus the common difference equals :-
x2 - x1 = x3 - x2 = x4 - x3 = 1
y2 - y1 = y3 - y2 = y4 - y3 = 0.38.
Thus the common difference is (1,0.38).

Answer:-2
Step-by-step explanation:x=-2
F(x) = 2x²+3x
g(x)= x-2
f(x)+ g(x) =( 2x²+3x ) +(x-2)
= 2x²+3x+x-2
= 2x²+4x-2
(f+g)(2) = 2(2)²+4(2)-2
= 2•4+8-2
= 8+8-2
= 14

a. Solve the formula:
P = 2L + 2W
-2L = -P + 2W
ANSWER FOR A: L = (P/2) - W
b. Substitute the values:
L = (48/2) - 6
Simplify:
L = 24 - 6
L = 18
So the length is 18 feet.
