Answer:
72 m²
Step-by-step explanation:
A = 4x(5+4+5) + (4x4)
= 4x14 + 16
= 56 + 16
= 72 m²
Answer:
y = –1 + 3x
Step-by-step explanation:
To know which option is correct, we shall use the equation given in each option to see which will validate the table. This is illustrated below:
Option 1
y = –1x + 3
x = –2
y = –1(–2) + 3
y = 2 + 3
y = 5
This did not give the required value of y (i.e –7) in the table.
Option 2
y = 1 + 3x
x = –2
y = 1 + 3(–2)
y = 1 – 6
y = –5
This did not give the required value of y (i.e –7) in the table.
Option 3
y = –3 + 1x
x = –2
y = –3 + 1(–2)
y = –3 – 2
y = –5
This did not give the required value of y (i.e –7) in the table.
Option 4
y = –1 + 3x
x = –2
y = –1 + 3(–2)
y = –1 – 6
y = –7
This gives the required value of y (i.e –7) in the table.
Thus, the equation that matches the table is:
y = –1 + 3x
Answer:
208
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
2x - 5 = 5
To solve this, we need to isolate x in all terms. First off, add 5 to both sides:
2x - 5 = 5
2x = 10
Divide 2 by both sides:
2x = 10
x = 5
