Answer:
Explanation:
opposite angles in a quadrilateral sum up to 180°
total interior angles in a quadrilateral is 360°
solve for x:
x - 2 + x + 2 = 180°
2x = 180°
x = 90°
solve for each angle:
1st
x + 2
90° + 2 = 92°
2nd
x - 2
90° - 2 = 88°
3rd
x - 10
90° - 10° = 80°
4th
360° - 80° - 88° - 92° = 100°
The product is the answer you get from multiplying. The parentheses acts like a multiplication sign.
(–7)(–4)
–7 × –4 = 28
The answer is 28.
Answer:
x=-3
Step-by-step explanation:
we know that
The slope of a vertical line is undefined
The formula to calculate the slope between two points is equal to
we have
A(x+14, 5) and B(2−3x, 8)
substitute
so
If the slope is undefined
then
The denominator must be equal to zero
solve for x
answer:
1/10 as a fraction or if you want it as a decimal it would be 0.1
step-by-step explanation:
-4(x-4)- 3=12+6x after seeing you multiply -4 by x and -4
and you would get
-4x+0-3=12+6x and then you distribute all the way and you would get
1/10 or if you dont want a fraction and want a decimal is would be 0.1
Some equivalent fractions of 1/20 are:
<span>1/20 = 2/40 = 3/60 = 4/80 = 5/100 = 6/120 = 7/140 = 8/160 = 9/180 = 10/200 = 11/220 = 12/240 = 13/260 = 14/280 = 15/300 = 16/320 = 17/340 = 18/360 = 19/380 = 20/400</span>
