If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to
... (x +3)² = 0
This multiplies out to give
... x² +6x +9 = 0
The value of m is 6.
_____
For finding the square of a binomial, you can either use the special form you have memorized:
... (x +a)² + x² +2ax + a²
or you can use the distributive property.
... (x +a)² = x(x +a) +a(x +a)
... = x² +ax +ax +a² = x² +2ax +a²
Volume= area of base x height
base= 3.14 x 4^2(8/2=4 for the radius)
base=50.24
base x height=50.24 x 23=1155.52, or 1156 ft3
Answer C
Step-by-step explanation:
An all-in-one account that includes savings, checking, borrowing, investing, and other financial services for a single fee; also called a cash management account.
x = 27° (A)
Step-by-step explanation:
5x° + (x + 18)° = 180°
(5x + x)° + 18° = 180°
6x° + 18° = 180°
6x° = 180° - 18°
6x° = 162°
x° = 162 ÷ 6
x° = <u>2</u><u>7</u><u>°</u>
So, the value of x is 27° (A)
