Answer:
<u><em>x>2</em></u>
Step-by-step explanation:
<u><em>x3+3x2=7x+6</em></u>
<u><em>x3+3x2−(7x+6)=7x+6−(7x+6)</em></u>
<u><em>x3+3x2−7x−6=0</em></u>
<u><em>(x−2)(x2+5x+3)=0</em></u>
<u><em>x−2=0 or x2+5x+3=0</em></u>
<u><em>x=2 or x=−0.6972243622680054 or x=−4.302775637731995</em></u>
<u><em>x<−4.302776</em></u>
<u><em>−4.302776<x<−0.697224</em></u>
<u><em>−0.697224<x<2</em></u>
<u><em>x>2(Works in original inequality)</em></u>
Answer:

Solution
A=bh=5·6=30
Answer:
Step-by-step explanation:
from the graph of f(x)
when x=1,f(x)=0
or f(1)=0
when f(x)=2,x=2
for g(x)
when x=6,g(x)=16
or g(6)=16
when g(x)=18,x=32
for h(x)
when x=14
h(x)=27x-7
h(14)=27×14-7=7(27×2-1)=7(54-1)=7×53=371
h(x)=-493
27x-7=-493
27 x=-493+7=-486
3 x=-54
x=-18
for p(t)
when t=94
p(t)=24
p(94)=24
p(t)=67
t=31
I'm assuming that the 1/3 is an exponent.
If so, then
![2^{1/3} = \sqrt[3]{2}](https://tex.z-dn.net/?f=2%5E%7B1%2F3%7D%20%3D%20%5Csqrt%5B3%5D%7B2%7D)
Which is the cube root of 2. Raising any value to the 1/3 power is the same as taking the cube root.
Answer:
x = 6
y = 0
Explanation:
−2x+y=−12;3y−2x=−12
Rewrite equations:
−2x+y=−12;−2x+3y=−12
Solve −2x+y=−12 for y
−2x+y=−12
−2x+y+2x=−12+2x(Add 2x to both sides)
y=2x−12
Substitute 2x−12 for y in −2x+3y=−12
−2x+3y=−12
−2x+3(2x−12)=−12
4x−36=−12 (Simplify both sides of the equation)
4x−36+36=−12+36 (Add 36 to both sides)
4x=24
Divide both sides by 4
4x / 4 = 24 / 4
x = 6
Substitute 6 for x in y=2x−12
y=2x−12
y=(2)(6)−12
y=0 (Simplify both sides of the equation)
