Answer:
Rectangle has two(2) lines of reflections
A square has four(4) lines of reflections
Step-by-step explanation:
Lines of reflection also known as lines of symmetry ,
In a rectangle there are two( 2) lines of symmetry and they are found along the midpoints of the opposite side of the rectangle, while for A square there are four (4) lines of reflections which can be seen along the midpoint of the opposite sides of the square and also along the midpoint of the opposite vertices of the square.
10^3 = 1000
2^3 = 8
3^2 = 9
2^5 = 32
4^3 = 64
7^3 = 343
5^2 = 25
3^4 = 81
that’s all the ones i know :)
Way 1:
a triangle with sides 3,4,5 will make a triangle. because this isn't 3,4,5 triangle it wont work.
way 2:
By using Heron's formula you can find the area of the flower bed.
<span>s=(a+b+c) ÷2
</span><span>Area =√s(s-a)(s-b)(s-c)
</span>so, 3+4+8= 15
15÷2 =7.5
√7.5(7.5-3)(7.5-4)(<span>7.5-8)
</span>Now because 7.5-8 gives you a negative number and you can't have a negative number under a square root unless you want to use an imaginary number, it won't form a triangle.
Answer:
right the box in the corner means it's a 90 degree angle or a right angle
Answer:
A
Step-by-step explanation:
Check the solution by substituting x = 
into the left side of the equation
2sin²x - sinx - 1
= 2sin²( ) - sin ( ) - 1
= 2(1)² - 1 - 1
= 2 - 1 - 1
= 0
= right side
is therefore a solution to the equation
