d.51(4)-24=180
Answer:
x = 21.5
Step-by-step explanation:
In the given trapezoid, the angles are consecutive interior angles.
i.e, consider the parallel sides of a trapezoid as parallel lines and the common side as the transversal. So, it is parallel lines cut by a transversal make a pair of consecutive interior angles which are supplementary.
i.e,
(5x + 13)° + (3x - 5)° =180°
5x + 13 + 3x - 5 = 180
8x + 8 = 180
8x = 180 - 8 =172
x= 172/8 = 21.5
So, 5x + 13 = 5(21.5) + 13 = 120.5°
3x - 5 = 3(21.5) -5 = 59.5°
Extranious solution is mostly when you take the square root of negative number
what you want to do is math stuff
translate
remember that
so
7.
add 2 to both sides
square both sides
cube root both sides
x+1=9
minus 1
x=8
8.
square both sides
using math
0=x²-5x-6
x=6 or -1
if we do x=-1, we get
√4=-2, which is kind of true, but we normally find the principal root (posiitive0
-1 is extraious
x=6
9.
add √(x-1) to both sides then square both sides
minus (x+5) from both sides
square both sides
using math
x=-1 or 15
if we had x=-1, we would be having √(-1-1) which is sqrt of negative which is not allowed
x=15
Simple,
The Y inctercept.
To find the Y intercept we know x=0 because the graph crosses the y axis when x axis is 0 so.
Y=4x-2
Y=4(0)-2
Y=-2 y interecpt is -2
The x intercept.
To find the X intercept we know y=0 because the graph crosses the x axis when y axis is 0 so.
Y=4x-2
0=4x-2
2=4x
2/4 = x x intercept is 2/4 or 0.5
Answer: 24
To calculate with long division when the divisor is a decimal, add zeroes in both the dividend and divisor. This means you get 360 ÷ 15.
From here, just do normal calculation and you get 24 as your answer.
