Answer:
-11 and -10
Step-by-step explanation:
-11² = -121
-(√119)² = -119
-10² = -100
_____
-√119 is between -11 and -10
AD || BC
<span>• AB = CD </span>
<span>• ∠BAD = ∠CDA (a given condition ∵ ABCD is an isosceles trapezium) </span>
<span>The diagonals AC and BD create two ∆'s: ∆ABD, and ∆ACD </span>
<span>The two ∆'s are congruent (SAS). </span>
<span>(S): AB = CD </span>
<span>(A): ∠BAD = ∠CDA
</span><span>(S): AD = DA (common side) </span>
<span>
The corresponding sides of the two ∆'s, BD and AC, are also congruent. </span>
<span>(the two diagonals of the trapezium/trapezoid)
</span>
Answer:
Marsha must pay in 2 years
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the amount of money to pay
P is amount of money borrowed
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
therefore
Marsha must pay in 2 years
Answer:
a = 3
Step-by-step explanation:
First start writing out the binomial expansion of 
![[1^7] + [7C1 * 1^6 *(ax)] + [7C2*1^5*(ax)^2]+[7C3*1^4*(ax)^3]](https://tex.z-dn.net/?f=%5B1%5E7%5D%20%2B%20%5B7C1%20%2A%201%5E6%20%2A%28ax%29%5D%20%2B%20%5B7C2%2A1%5E5%2A%28ax%29%5E2%5D%2B%5B7C3%2A1%5E4%2A%28ax%29%5E3%5D)
as you can see from this, the last bracket will produce our
term
