F(3)=-18
You just replace x for three for your equation and then use Ofer of operations to solve it.
So f(3)= 21+ 2(3)-5(3)^2
The exponent goes first: f(3)= 21+ 2(3)-5(9)
Next is multiplication: f(3)= 21+ 6-45
Now add: f(3)= 27-45
Finally subtract: f(3)= -18
Hope this helps!
Answer:
The answer would be X=24
Step-by-step explanation:
Y is multiplied by 3 to get the answer 30. Because they are varied directly you have to multiply the 8 by 3 to get your answer!

Answer:
Simplify the expression.

Step-by-step explanation:
got it from mathaway
Step-by-step explanation:
1. In PQN & SRT.
a. <RST=<QPN (corresponding angle PQllSR)
b. <STR = <PNQ (corresponding angle TRIINQ)
c. TR=QN (Since TN & QN are opp. Side of parallelogram QNTR)
d. .°.PQN~=SRT.
2.PQN=PSOQ+SNO (whole part axiom)
3.SRT = SNO + NTRO(same as above)
4. PQN=SRT (From st. 1d)
or, PS0Q+SNO =SNO + NTRO (Cancellation of SNO)
or, PS0Q=NTRO
or, PSOQ +QOR=NTRO +QOR (Adding QOR on both side)
or, .°.◼️PQRS = ◼️QRTN
Best of luck!!!!.
EFGH is a dilation and rotation of ABCD.
The shortest side of the smaller figure corresponds to the shortest side of the largest one, the largest sides correspond, etc.
AB -> EF
BC-> FG
CD->GH
DA->HE
Corresponding angles are congruent in dilations.
Angle A = angle E
Angle B= angle F
Angle C = angle G
Angle D = angle H
Explanation:
EFGH is a dilation and rotation of ABCD. If you take one of the figures, rotate it 180 degrees, and lay it on top of the other figure, the corresponding sides and angles will line up.
