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:
1500
Step-by-step explanation:
To evaluate this expression, we simply plug the value of the variable into the expression and solve.
Since m = -4, plug a -4 in for m every time the m appears in the expression.
So we have (-4)^2 + 6(-4) + 3.
Start by simplifying the exponent.
(-4)^2 is 16.
Now multiply.
A positive times a negative is a negative.
So 6(-4) is -24.
So we have 16 + 24 + 3 which is 43.
Answer:
4/12 simplified is 1/3
3/4 > 1/3
Or, imagine this:
There are 2 pies, watermelons, pizzas, cookies, whatever fits you. One is cut into 4 pieces and the other into 3. You take the one with 4 pieces and your friend take the one with 3. When you finish, there is only 1 quarter left. However, your friend didn't even finish half. Of course, you ate more.
Weird example but who cares...
