Cut it in half (the top into a trapezoid and the bottom into another trapdoors then solve both and add them
Answer:
8
Step-by-step explanation:
8+12+4+3+14+1+9+13=64, 64/8=8
Answer:
⇒ The given quadratic equation is x2−kx+9=0, comparing it with ax2+bx+c=0
∴ We get, a=1b=−k,c=9
⇒ It is given that roots are real and distinct.
∴ b2−4ac>0
⇒ (−k)2−4(1)(9)>0
⇒ k2−36>0
⇒ k2>36
⇒ k>6 or k<−6
∴ We can see values of k given in question are correct.
Answer:
13
Step-by-step explanation:
1 1/3 = 4/3
18 ÷ 4/3
= 13
Answer:
a = 12m
Step-by-step explanation:
In order to solve this problem we will need to know the Pythagoras theorem that states that in a right angled triangle the square of the hypotenuse (the side opposite to the right angel) is equal to the sum of the squares of the other two sides. This theorem can be written as an equation....
Now we can see that we can easily find the missing value by using this theorem. We just have to substitute the values. And we get the following
