Answer:
1 equilateral triangle
Step-by-step explanation:
Given
Shape: Equilateral Triangle
Side length = 8cm
Required
Determine the number of triangles
From the question, we understand that the triangle is equilateral and the length of a side is 8cm.
This implies that the length of other sides will also be 8cm.
So, only one triangle can be constructed and their side lengths is 8cm.
Answer:
d. 28
Step-by-step explanation:
7<em>x</em> = 3<em>x</em> + 16
subtract 3<em>x</em> from both sides: 4<em>x</em> = 16
divide both sides by 4: <em>x</em> = 4
plug in four to find length of QA: 3 x (4) + 16 = 12 + 16 = 28
First, get the common denominator. Do this by multiplying 5/10 by 10
35/100 + 50/100 = 85/100
Then,simplify :
17/20
Hope this helps!
No its not a function :)
<span>to find the inverse function first expand those brackets </span>
<span>you'll get </span>
<span>f(x)= x^2 - 2x^2 - 2x^2 = 4x^2 </span>
<span>f(x)= x^2 - 4x^2 + 4x^2 </span>
<span>f(x)= x^2 or y=x^2 </span>
<span>to find the inverse, swap x and y around. then make y the subject again </span>
<span>y=x^2 </span>
<span>x=y^2 </span>
<span>Root of x=y </span>
<span>now put -1 into x </span>
<span>it wont work because roots cannot have negative numbers </span>
<span>answer is no</span>
