Answer:
x = 9
Step-by-step explanation:
x²-18x+91 = 10
x²-18x+81 = 0
(x-9)(x-9)= 0
x = 9
check:
9² - 18 (9) + 91
81-162+91 = 10
Answer:
A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
Answer:
(a) A trapezoid has only 1 pair of parallel sides but a parallelogram has 2
Step-by-step explanation:
Required
The difference between a trapezium and a parallelogram
The major difference is:
A trapezium has a pair of parallel side, the other sides are not parallel
A parallelogram has 4 sides where opposite sides are parallel (i.e 2 pairs of parallel sides).
<em>Hence, (a) is correct</em>
