Answer:
x=0
Step-by-step explanation:
-2x+9=9
-2x=9-9
-2x=0
x=0/-2
x=0
P(parentheses)
E(exponents)
M(multiplication)
D(division)
A(addition)
S(subtraction)
I did 2-
d) Square root of 16 plus 3 to the second power (exponent)
3 to the 2nd power = 9
square root of 16 is 4 so 9+4=13
g) Square root of 25 to the power of 2 + (2+3)
2+3= 5 then square root of 25 = 5 to the second power is 25 = 30
Answer:
steps below
Step-by-step explanation:
5th level of Pascal triangle: 1,5,10,10,5,1
(1+2x)⁵ = 1*1⁵*(2x)⁰+5*1⁴*2x+10*1³*(2x)²+10*1²*(2x)³+5*1¹(2x)⁴+1*1⁰*(2x)⁵
= 1 + 10x + 40x² + 80x³ + 80x⁴ + 32x⁵ .. (1)
(1-2x)⁵ = 1 - 10x + 40x² - 80x³ + 80x⁴ - 32x⁵ .. (2)
(1)+(2): (1+2x)⁵ + (1-2x)⁵ = 160x⁴ + 80x² +2
a + bx + cx ?? suppose it's ax⁴ + bx² + cx, if you have other set up.. adjust by yourself
<u>a = 160, b = 80, c = 2</u>
I think the answer is B. But if I’m wrong I am so sorry :(
