Answer:
Step-by-step explanation:
hello :
the x-intercepts when : y=0 means : 2x²--8x+5 =0
∆ = b² -4ac a=2 and b= -8 and c= 5
∆ = (-8)² -4(2)(5) = 64-40 =24
∆ >0 this equation has two solutions so : two x-intercepts
Answer:
9cm
Step-by-step explanation:
- Since PQST is a rectangle, ∠QST=∠QSR=∠90º. So triangle QSR is a right triangle.
- By the Pythagorean Theorem and that SR=6 and QR=10, we can say that 6^2+b^2=10^2. So, 36+b^2=100. And b^2=64 and b=8. So QS=8.
- Now we know that QS=PT=8.
- By the Pythagorean Theorem and that PR=17 and PT=8, we can say a^2+8^2=17^2. So, a^2+64=289. And a^2=225 and a=15.
- We know that TR=15 and SR=6 and TR-SR=TS, so 15-6=9.
The answer is d, the factor pairs of 24 are (1,24), (2,12), (3,8), and (4,6)
