Answer:
x2-2x-35
Final result :
(x + 5) • (x - 7)
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-2x-35
The first term is, x2 its coefficient is 1 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is -35
Step-1 : Multiply the coefficient of the first term by the constant 1 • -35 = -35
Step-2 : Find two factors of -35 whose sum equals the coefficient of the middle term, which is -2 .
-35 + 1 = -34
-7 + 5 = -2 That's it
Step-by-step explanation: 2+48-21
Final Result :
29
Answer:
5 + 4 - (8 * 3 - 22)⁴ * 4 = -55
Step-by-step explanation:
5 + 4 - (8 * 3 - 22)⁴ * 4
Follow PEMDAS which states you need to do equations in the order of:
Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Knowing this, simplify inside the parenthesis by multiplying 8 and 3 first.
5 + 4 - (24 - 22)⁴ * 4
Now subtract 22 from 24 inside the parenthesis.
5 + 4 - (2)⁴ * 4
Since we are done with parenthesis, move on to the next part of PEMDAS which says to do exponents next. Take 2 to the power of 4.
5 + 4 - 16 * 4
Now that we are done with exponents, move on to the next part of PEMDAS which says to multiply/divide next. Multiply -16 and 4.
5 + 4 - 64
Now that we are done with multiplication/division, move on to the last part of PEMDAS which says to add/subtract. Add 5 and 4.
9 - 64
Finally, subtract 64 from 9 to get:
-55.
A=pir^2
r=4
pi=3.14 for this problem
A=3.14(4^2)
A=3.14(16)
A=50.24 m^2

Answer:
s = 21.16
Step-by-step explanation:
0.5s +1= 7+ 4.58
Combine like terms
0.5s +1=11.58
Subtract 1 from each side
0.5s +1-1= 11.58-1
.5s = 10.58
Multiply by 2
.5s *2 = 10.58*2
s = 21.16
Answer:
let y = 0 and solve for the other variable, because any point on x-axis has y-coordinate = 0
