Answer:
40 + 3x + 4 + 3x + 4 = 180
48+6x=180
48 - 48 + 6x = 180 -4 8
6x = 132
6x/6 = 132/6
x = 22
Step-by-step explanation:
1. since the triangle is isosceles, angles A and C will have the same measures, so to solve for x, you can add another 3x + 4 or you can multiply A by 2.
2. add like terms
3. subtract
4. divide to get x
Answer:
All of them? Pls reply if so!
Step-by-step explanation:
To convert a fraction to a decimal just the divide the bottom into the top.
To convert a decimal into a fraction just put the decimal over 1 or divide the decimal by preference of tenths, hundredths, or thousandth place.
<span>Using processing software (Excel) or even a decent scientific calculator. You input the values and generate the best fit cubic equation.
For number 1, the equation is
y = 8x10</span>⁻⁵ x³ - 0.0097 x² + 0.374 x + 1.083
where x is the number of years since 1900
y is the pounds cheese consumed
For number 2, the equation is
y = -3x10⁻⁵ x³ + 0.0028 x² + 0.2155 x + 1.7736
For number 3
P(-1) = 18
Answer:
180’ - 130’
Step-by-step explanation:
Answer:
C=14pi cm
A=49pi cm^2
Step-by-step explanation:
1) Circumference of a circle is 2piR and R=7cm
C=2pi(7)
C=14pi cm
2) Area of a circle is piR^2 and R=7cm
A=pi (7)^2
A=49pi cm^2
