Answer:
12 in.
Step-by-step explanation:
You have to use the Pythagorean theorem for this problem. Since we are solving for DE, we do:
5 squared + b squared = 13 squared
25 + b squared = 169
Isolate the b:
25 - 25 + b squared = 169 - 25
b squared = 144
Find the square root of 144 = <u>12</u>
<u>(The formula for the Pyathagorean theorem is a squared + b squared = c squared) </u>
Answer:
7
Step-by-step explanation:
Set up an equation: x ^2 -3x=28
simplify to a quadratic equation. You would then solve and get x=7

Ur multiplying each number by 2 to find the next number..
1,2,4,8,16,32,64,128,256...answer C
By Pythagoras Theorem,
Height of Triangle = (1.7^2-1^2)^0.5 = (1.89)^0.5= 1.37 in
Area of one triangle = 1.374772708* 2*0.5= 1.374772708in^2
area of polygon = 5*1.374772708in^2=6.87in^2 = 6.9in^2
answer is b
Answer:
2nd option
y > 6 and y < 2
Step-by-step explanation:
as the value of y can not be greater than 6 and less than 2 at the same time, the 2 inequalities have no common solutions
theefore no solution
