Answer:
B. 10.9
Step-by-step explanation:
Area of triangle= 1/2*24*h
∠N=90° ⇒ Area of triangle= 1/2*MN*ON
MN²= h²+(24-7)²
ON²= h²+7²
- 24h=MN*ON
- 24h= √h²+(24-7)²*√h²+7²
- (24h)²=(h²+17²)(h²+7²)
- 576k=k²+289k+49k+289*49
- k²-238k+14161=0
Answer:
(x-8)(x-6)
Step-by-step explanation:
To factor this, you need the numbers that will multiply together to give you the third number (48 in this case) and add together to give you the second number (-14). -8 * -6 = 48. -8 + -6 = -14
Answer:
4×5
3×2
Step-by-step explanation:
a+b=8 or a=8-b
4a+2b=26
4(8-b)+2b=26
32-4b+2b=26
32-2b=26
32-26=2b
6=2b
b=3
a=8-3
a=5
