Answer:
x = -6
Step-by-step explanation:
3(x+4)-1=-7
Add 1 to each side
3(x+4)-1+1=-7+1
3(x+4)=-6
Divide by 3
3/3(x+4)=-6/3
x+4 = -2
Subtract 4 from each side
x+4-4 = -2-4
x = -6
Answer:
3
Step-by-step explanation:
You know that ...
1000 = 10³
when you take the logarithm to base 10, you get
log₁₀(1000) = 3
Answer:
90°
Step-by-step explanation:
Since they are vertical angles, they equal eachother
4x+15=5x-5
add the 5 to both sides
4x+19=5x
subtract the 4x from both sides
x=19
Then you have to plug in 19 to find the measure of ZA
4(19)+14
76+14
90
2x multiplies to all numbers:
2x x 8x3 = 16x4
2x x 6x2 = 12x3
2x x -10x = -20x2
Answer: 16x4 + 12x³ - 20x²
Hope this helps :)
