Answer:
x = 7
Step-by-step explanation:
9 get subtracted on both sides and then 16-9 is 7
Answer:
Step-by-step explanation:
The co-ordinates of the rectangle are:
A (8, 6)
B (-4, -10)
C (-8, -7)
D (4, 9)
The Area of Rectangle is Given by: <em>length x breadth </em>= AB x BC
Lengths of AB and BC can be found by distance formula
<em>length</em>(AB) =
= ![\sqrt{(-4-8)^{2} + (-10-6)^{2}} = 20](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4-8%29%5E%7B2%7D%20%2B%20%28-10-6%29%5E%7B2%7D%7D%20%3D%2020)
Similarly,
<em>length</em>(BC) = 5
Area of Rectangle = AB x BC = 20 x 5 = 100 square units
Answer:
2x + 6
Step-by-step explanation:
2 will multiply everything inside the bracket.
2 x X =2x
2 X 3=6
Answer:
She increased 80% the practise time
Step-by-step explanation:
The question is incomplete, the following is missing:
<em>by how much did she increase the time she practised each day?
</em>
From Monday to Wednesday she increased 90 - 50 = 40 minutes the practise time.
To compute the increment as a percentage use: increment/reference *100
In this case, that is: 40/50*100 = 80%, where 50 minutes is taken as a reference.
