Answer:
using a negative facto to factor the expression will be:
- 7a+49b - 35 = -7(a-7b+5)
Step-by-step explanation:
Given the expression
- 7a+49b - 35
Rewrite -35 as 5 · 7
Rewrite 49 as 7 · 7
so
= -7a + 7 · 7b - 5 · 7
as -7 is the common factor, so factoring out
= -7(a-7b+5)
Thus, using a negative facto to factor the expression will be:
- 7a+49b - 35 = -7(a-7b+5)
Question 1)
Given the function
f(x) = 2|x+10| - 6
You need to remember that:
f(x) = y
f(0) means we need to determine the value of y at x = 0.
so substitute x = 0 in the function
Apply absolute value:
Thus,
Question 2)
Given the fuction
g(x) = x+1
substitute g(x) = 20 in the function
20 = x+1
x = 20-1
x = 19
Thus,
x = 0
Question 3)
Given the function
f(x)=2|x+10|-6
substitute x = 1 in the function
f(1)=2|1+10|-6
f(1)=2|1+10|-6
f(1) = 2|11| - 6
Apply absolute value:
f(1) = 2(11) - 6
f(1) = 22 - 6
f(1) = 16
Given the function
g(x)=x+1
substitute x = 0 in the function
g(0) = 0+1
g(0) = 1
Thus,
g(0)+f(1) = 16+1
= 17

Answer:
Width = 3ft
Length = 11ft
Step-by-step explanation:
Given parameters:
Area of rectangular wall = 33ft²
Unknown:
Length and width of the wall of the barn = ?
Solution:
So;
Area of a rectangle = length x width
Let the length = L
width = W
L = 8 + W
33 = (8 + W)W
33 = 8W + W²
W² + 8W - 33 = 0
W² + 11W - 3W - 33 = 0
W(W + 11) - 3(W + 11) = 0
(W - 3)(W + 11) = 0
W - 3 = 0 or W + 11 = 0
So; W = 3
To find the length;
L = W + 8
L = 3 + 8 = 11
