Answer:
for a, look at my picture
b = 19.5 inches
Step-by-step explanation:
A is simple. thats my take on it, but other people coudl've drawn it differently
B is more difficult. I made triangle QRS like that so i can make a ratio.
My ratio:
QX:QY = QR:QS
8:12=13:QS
13*12 = 8*QS
156/8 = 19.5
therefore 19.5 inches
First statement: False. Points K, M and N form a triangle.
Second statement: True. Points J, K, and Q are on the same line.
Third statement: False. KN and MQ intersect at N, not at R.
Fourth statement: False. JQ and KM intersect at K, but MQ does not pass through it.
Fifth statement: True. By definition, there is always only 1 line that can be drawn between 2 given points.
Answer:
39
Step-by-step explanation:
g(x)= -2x+2 and f(x)= 3x^2+4
(g+f)(-3)
g(-3) = -2(-3) +2 = 6+2 =8
f(-3) = 3 (-3)^2 +4 = 3(9)+4 = 27+4 = 31
(g+f)(-3) = g(-3) + f(-3) = 8+31 = 39
