The base is an equilateral triangle. The formula of the area of that triangle is:
a - length of side
a = 3". Substitute:
The lateral side is a rectangle.
The Total Area is equal the sum of two times of Base and three times of Lateral Side.
Answer:
B
Step-by-step explanation:
x² - 4x - 7 = 0
(x - 2)² = 11
I don't know if I did it right but if u multiply 8 by 24 u get 192 I hope I helped <span />
Step-by-step explanation:Step 1: Simplify both sides of the equation.
4−(2y−1)=2(5y+9)+y
4+−1(2y−1)=2(5y+9)+y(Distribute the Negative Sign)
4+−1(2y)+(−1)(−1)=2(5y+9)+y
4+−2y+1=2(5y+9)+y
4+−2y+1=(2)(5y)+(2)(9)+y(Distribute)
4+−2y+1=10y+18+y
(−2y)+(4+1)=(10y+y)+(18)(Combine Like Terms)
−2y+5=11y+18
−2y+5=11y+18
Step 2: Subtract 11y from both sides.
−2y+5−11y=11y+18−11y
−13y+5=18
Step 3: Subtract 5 from both sides.
−13y+5−5=18−5
−13y=13
Step 4: Divide both sides by -13.
−13y
−13
=
13
−13
y=−1
Answer: y =-1

Step-by-step explanation:
If f(x) is an even function, then
f(x) = f(- x)
f(- x) = (- x)³ + 5(- x) + 1 = - x³ - 5x + 1 ≠ x³ + 5x + 1
Thus f(x) is not an even function
