Answer:
Step-by-step explanation:
1 .
- x - 8 < 13
- x < 8 + 13
- x < 21
2.
- x - 8 > -13
- x > 8 - 13
- x > -5
<u>Combined answer</u>
Answer:
see explanation
Step-by-step explanation:
Given
4x - 8x ÷ 2
Under the rules of PEMDAS , division must be performed before subtraction.
Hence
4x - 8x ÷ 2 = 4x - 4x ← dividing - 8x by 2, then
4x - 4x = 0 ← correct answer
Answer: The surface area of the triangular prism is 448 square millimeters.
To find the surface area, we just need to input our values into the formula that is given.
SA = 2B + Ph
SA = 2(84) + 56(5)
SA = 168 + 280
SA = 448
The final surface area is 448 mm^2.
Answer:
The value of k is -11
Step-by-step explanation:
If (x+2) is a factor of x3 − 6x2 + kx + 10:
Then,
f(x)=x3 − 6x2 + kx + 10
f(-2)=0
f(-2)=(-2)³-6(-2)²+k(-2)+10=0
f(-2)= -8-6(4)-2k+10=0
f(-2)= -8-24-2k+10=0
Solve the like terms:
f(-2)=-2k-22=0
f(-2)=-2k=0+22
-2k=22
k=22/-2
k=-11
Hence the value of k is -11....
