Answer:
Step-by-step explanation:
8t = 10(1/2t) + 27
8(2t = 10(t) + 27
Number 4 is correct
Answer:
x = (-9)
Step-by-step explanation:
From the diagram, we see that the triangle is an isosceles triangle. Since it is an isosceles triangle we know that the angles at the base of an isosceles triangle are equal to each other, so the angles that is not marked will be equal to m∠2. Since now we know that, we can make the following equation...
m∠2 + m∠2 + 84 = 180
Now we solve it and get...
2(m∠2) = 180 - 84
2(m∠2) = 96
m∠2 = 48
Now we substitute m∠2 with x + 57, and get...
m∠2 = 48
x + 57 = 48
x = 48 - 57
x = (-9)
Answer:
(3x2 + 1) • (4x - 1)
Step-by-step explanation:
Equation at the end of step 1 :
(((12 • (x3)) - 3x2) + 4x) - 1
Equation at the end of step 2 :
(((22•3x3) - 3x2) + 4x) - 1
Checking for a perfect cube :
12x3-3x2+4x-1 is not a perfect cube
Trying to factor by pulling out :
Factoring: 12x3-3x2+4x-1
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 4x-1
Group 2: 12x3-3x2
Pull out from each group separately :
Group 1: (4x-1) • (1)
Group 2: (4x-1) • (3x2)
-------------------
Add up the two groups :
(4x-1) • (3x2+1)
Final result :
(3x2 + 1) • (4x - 1)
