<u>85 + c/4 = 99</u>
Subtract 85 from each side: c/4 = 14
Multiply each side by 4 : <em> c = 56
</em>
Answer:
y = x² − 6x − 27
Step-by-step explanation:
To distribute, you can use something called FOIL. It stands for First, Outer, Inner, Last.
First, multiply the First term in each factor.
x · x = x²
Now multiply the Outer terms in each factor.
x · 3 = 3x
Next multiply the Inner terms in each factor.
-9 · x = -9x
Finally, multiply the Last terms in each factor.
-9 · 3 = -27
Add them all up:
x² + 3x − 9x − 27
x² − 6x − 27
Given that the metal strip is being installed around a bench that 6ft long 2ft wide. The metal required will be given by:
P=4(L+W)
=4(6+2)
=4(8)
=32 ft
Therefore we conclude that we need a metal strip that is 32ft long
1)
LHS:

LHS = RHS. So, the statement is true
2)
LHS:

LHS not equal to RHS. So, the statement is false
3)
LHS:

LHS = RHS. So, the statement is true.
4)
LHS:

LHS = RHS. So, the statement is true.
