Step-by-step explanation:
1.) x + 37 + x + 67 + 90 = 180
combine like terms
2x +194 = 180
subtract 194 both sides
2x = -14
x = -7
2.) 63 + 86 = x
x = 149
Answer:
B = 2
Step-by-step explanation:
Factor the left side
2x² - 12xy - 32y² ← factor out 2 from each term
= 2(x² - 6xy - 16y²)
Consider the factors of the coefficient of the y² term (- 16) which sum to give the coefficient of the xy- term (- 6)
The factors are - 8 and + 2, since
- 8 × 2 = - 16 and - 8 + 2 = - 6, thus
x² - 6xy - 16y² = (x - 8y)(x + 2y)
and
2x² - 12xy - 32y² = 2(x - 8y)(x + 2y) ← in factored form
Compare the factored form to the right side
Thus B = 2

Step-by-step explanation:
a _is used to show the correlation between two sets of value
The function of the polynomial is (b)
From the graph, we have the following highlights
- The graph crosses the x-axis at x = -1 and x = 3
- The graph touches the x-axis at x = -2
The above highlights mean that:
- The function has a multiplicity of 1 at x = -1 and x = 3
- The function has a multiplicity of 2 at x = -2
So, the function of the polynomial is:
Assume a = 1.
So, we have:
Multiply
Hence, the function of the polynomial is (b)
