Answer:
x > 10
Step-by-step explanation:
x-3 > 7
Add 3 to each side
x-3+3 > 7+3
x > 10
Answer:
3
Step-by-step explanation:
The sum of these two polynomials is - 2 x^2 - 3. the two x variables are additive inverses and -6 x^2 and 4 x^2 equal - 2 x^2 and -3 results from -4 and 1
Multiplying the sum by 2 gives us - 4 x^2 - 6 . Answer 3
Answer:
b² +12b +32 = (b+4)(b+8)
Step-by-step explanation:
The product of binomial factors (x+a) and (x+b) is ...
(x+a)(x+b) = x² +ax +bx +ab
= x² + (a+b)x + ab
That is, the coefficient of x is the sum of factors of the constant term.
In order to determine "a" and "b", you can look at the factors of 32 and see which pair has a sum that is 12.
32 = 1×32 = 2×16 = 4×8
The last factor pair has a sum that is 12, so your factorization can be
b² +12b +32 = (b+4)(b+8)
Answer: see proof below
<u>Step-by-step explanation:</u>
Use the following Double Angle Identities: cos 2A = 1 - 2sin²A
sin 2A = 2sinA · cosA
<u>Proof LHS = RHS</u>
y cos 2A + x sin 2A = y
x sin 2A = y - y cos 2A
x sin 2A = y(1 - cos 2A)
This is a TRUE statement since it was given that
