Step-by-step explanation:
7a
x2 + 4x + ax + 4a
x2 + ax + 4x + 4a
x (x + a) + 4 (x + a)
:(x + 4)(x+a)
7d
x2+2x-ax-2a
x2-ax+2x-2a
x (x-a)+2 (x-a)
:(x+2)(x-a)
7h
x2-2bx-5x+10b
x2-5x-2bx+10b
x (x-5)-2b(x-5)
:(x-2b)(x-5)
Answer:
c) G= (4,0)
Step-by-step explanation:
Point A (-5,0) and point E is (7,4)
Point A (-5,0) and point E is (7,4)
A is on x axis so F is also on x axis. So F is (7,0)
AE is divided into 4 equal parts
First we find the distance between A and F. Then divide it by 4
A is (-5,0) and F is (7,0)
Distance = 7 -(-5) = 12
Now divide it by 4 so 12/ 4= 3
We subtract 3 from point F(7,0) to get point G
G= (7-3,0)
G= (4,0)

Answer:
2(b+1+b)= 18
Step-by-step explanation:
Perimeter of a rectangle= 2(l+b)
18 feet= 2(l+b)
length: l, breadth: b
Because the length of the sandbox is 1 foot longer, it will be:
b+1 = l
Substitute l with b+1
2(b+1+b)= 18
