Answer:
2x + 2y = 4 does not belong
Step-by-step explanation:
2x + y = 4 → <u>y = -2x + 4</u>
y = -2x + 4 → <u>y = -2x + 4</u>
f(x) = -2x + 4 → <u>y = -2x + 4</u>
2x + 2y = 4 → <u>y = -x + 2</u>
Answer: (x-2) inches.
The question asks for length in square inches. There is no such thing. It should read in inches. Since it is a square frame, we can take the square root of (x^2-4x+4), which is (x-4). This is in incnes
Step-by-step explanation:
(x-4)*(x-4) = x^2-4x+4
Answer:
C. 13
Step-by-step explanation:
from on online source, the question should be placed as thus:
Of the following integers, which is the closest approximation to (√2 + √5)^2 ?
A. 7
B. 10
C. 13
D. 15
E. 17
This is known as Algebraic expression. So we have to expand to simplify further
using this identity th (a+b)^2 = a^2 + b^2 +2ab
(√2 + √5)^2 =
(√2 + √5)(√2 + √5)
................Expansion of the above

2 + 5 + 2√10
~ 2 +5 + 2(3)
C. 13
Answer:
f
Step-by-step explanation:
