Answer:
128
Step-by-step explanation:
There is a common difference between consecutive terms, that is
11 - 2 = 20 - 11 = 9
This indicates the sequence is arithmetic with n th term
= t₁ + (n - 1)d
where t₁ is the first term and d the common difference
Here t₁ = 2 and d = 9 , thus
t₁₅ = 2 + (14 × 9) = 2 + 126 = 128
Answer:
x=4
Step-by-step explanation:
(-x+3)-(x-5)=2x+8
(-x+3)+(-x+5)=2x+8
-x+3-x+5=2x-8
-2x+8=2x-8
-2x-2x=-8-8
-4x=-16
x=-16/-4
x=4
Hey there! I’m happy to help!
We see that the two equal sides are longer than the base. This means that our a will be larger than b. The problem says that one of the longer sides is 6.3. Since the two longer sides are equal, that means that both longer sides are 6.3 cm. Therefore, we can simply subtract these two from the perimeter to find the shorter side, which is the base.
15.7-6.3-6.3=3.1
Therefore, the length of the base is 3.1 cm.
I hope that this helps!
I’m not sure if it’s right but this is what i got
