Answer:
Pentagon G'P'E'S'T' is smaller than pentagon pentagon GPEST because the scale factor is less than 1.
Step-by-step explanation:
Sorry im late homie
S10 = -150;
<span> the sum of next 10 terms = S20 - S10 => -550 = S20 + 150 => S20 = -700;
</span>S10 = -150 => 2a1 + 9r = -30;
S20 = -700 => 2a1 + 19r = -70;
Then 10r = -40 => r = -4 , and, 2a1 -36 = -30 => 2a1 = 6 => a1 = 3;
Well, if 10 people are heading to the park and each car holds 5 people, we can write the equation, "5x = 10" so, we need to get x by itself. To do that we need to get rid of the five. Whatever we do to one side, we do to the other. So 5/10 = 2 so, 2 cars are needed. Hope that helps! :)
