5^2 +12^2= diagonal^2
25+144=d^2
169= d^2
D= 13
Answer:
(B) -1
Step-by-step explanation:
We want to determine the rational number which is one tick mark to the left of 
.
If the number is to the left, it must be less than .
Since there are 4 equal spaces between each number, the numbers between -1 and 0 are:
We can then see that the number one tick to the left of is -1.
The correct option is B.
Answer:
its C (Species diversity)
Step-by-step explanation:
Answer:
The "x" value is 7
Step-by-step explanation:
If the shape in the image is a rhombus then we know that GI is consisted of two KI's. So now we can write the following equation....
GI = (2)(KI)
23x - 33 = (2)(6x + 22)
23x - 33 = 12x + 44
23x = 12x + 77
11x = 77
x = 7
Okay so question is
x^2-10x + 26 = 8
Lets simplify it
x^2-10x+18=0
Let's solve your equation step-by-step.<span><span><span><span>x2</span>−<span>10x</span></span>+18</span>=0
</span>Step 1: Use quadratic formula with a=1, b=-10, c=18.<span>x=<span><span><span>−b</span>±<span>√<span><span>b2</span>−<span><span>4a</span>c</span></span></span></span><span>2a
