Can someone please help me with this?

Answer:

$S_{13}$ = 403

Step-by-step explanation:

the sum to n terms of an arithmetic series is

$S_{n}$ = $\frac{n}{2}$ (a + l) ← a is the first term and l the last term

here a = - 5 and l = 67 , then

$S_{13}$ = $\frac{13}{2}$ (- 5 + 67) = 6.5 × 62 = 403

Write the following proportion: 8 is to 64 as 2 is to x.

x = 4

8 multiplied by itself is 64.
And so, 2 times itself is 4.

a square has the side measurment of s = 2 3 over 2 using the formula 1= s^2 find the area of the square

vitfil [10]

Check the picture below.

$\bf A=s^2\qquad s=2\frac{3}{2}\qquad A=\left( 2\frac{3}{2} \right)^2\implies A=\left( \frac{2\cdot 2+3}{2} \right)^2
\\\\\\
A=\left( \frac{7}{2} \right)^2\implies A=\cfrac{7^2}{2^2}\implies A=\cfrac{49}{4}\implies A=12\frac{1}{4}$
