Step-by-step explanation:
1 . when we collect like terms we only focus on the variables and the power of the variable I f exist so in this question the answer is 8x^2 because both have the same variable and same power or exponent.
2. one term is monomial
two terms is binomial
3. b
4. -9
5. c
1 is 1,530 if you need help with 2 I’ll help u with that also
Photomath i use it for my math all the time it gives you the option for how you wanna solve it and shows you how to solve it
We know that formula for circumference is 2πr
Since we have circumference of 2π, that would means 2π = 2πr.
We need to solve for r. We can divide both sides by 2π:
2π / 2π = 2πr / 2π
1 = r
So radius is 1.
Now the formula for area of circle is πr². So plug in r=1 and that would be
π(1)²
π
So area of circle is π.
Hope this helps.
15 is 37.5% of 40
<em>Equation: Y = P% * X</em>
<em />
P% = Y/X
P% = 15/40
p = 0.375
0.375 × 100 = 37.5%
