Answer:
2x^2+14x-240=0
Step-by-step explanation:
Remember Pythagoras's theorem?
a^2+b^2=c^2
So over here,
x^2+ (x+7)^2= 17^2 [ we need to now simplify (x+7)^2 --> (x+7) (x+7) ]
x^2+ x^2+7x+7x+49= 289
2x^2+ 14x+49= 289
2x^2+14x+49=0 [ we need to make the right side zero coz thats
the rule for ]
2x^2+14x-240=0
(idk, but i think the "show that x^2.....) is wrong)
Answer:
Step-by-step explanation:
9/100 i believe as you would multiply 3/10 by 3/10 due to the fact the marble is being replaced so the probability of getting a red marble the second time will be more unlikely. If I'm right please thank me or give me brainly. Hope this helps :)
Answer:
43.5 cm² and 112 cm²
Step-by-step explanation:
Here the instructions aren't given what to do. So I am finding the area of the ∆s .
<u>Area </u><u>of</u><u> </u><u>first </u><u>∆</u><u> </u><u>:</u><u>-</u><u> </u>
- A = 1/2 * b * h
- A = 1/2 * 14.5 cm * 6cm
- A = 3 × 14.5 cm²
- A = 43.5 cm²
<u>Area </u><u>of</u><u> </u><u>second</u><u> </u><u>∆</u><u> </u><u>:</u><u>-</u><u> </u>
- A = 1/2 * ( sum of || sides) * h
- A = 1/2 * ( 9 cm + 19cm) * 8cm
- A = 4cm * 28cm
- A = 112 cm²
