Perimeter of square = 4*8x=32x
Perimeter of rectangle = 2*(5x+8)+2*10=10x+16+20=10x+36
32x=10x+36
22x=36
x=36/22
P=4*8*36/22=2*8*36/11= 56.36 units

F(x) = 16ˣ

A. g(x) = 8(2ˣ)
    g(x) = (2³)(2ˣ)
    g(x) = 2ˣ⁺³
The answer is not A.

B. g(x) = 4096(16ˣ⁻³)
    g(x) = (16³)(16ˣ⁻³)
    g(x) = 16ˣ
The answer is B.

C. g(x) = 4(4ˣ)
     g(x) = 4ˣ⁺¹
The answer is not C.

D. g(x) = 0.0625(16ˣ⁺¹)
     g(x) = (16⁻¹)(16ˣ⁺¹)
     g(x) = 16ˣ
The answer is D.

E. g(x) = 32(16ˣ⁻²)
    g(x) = (2⁵)(2⁴ˣ⁻⁸)
    g(x) = 2(⁴ˣ⁻³)
The answer is not E.

F. g(x) = 2(8ˣ)
    g(x) = 2(2³ˣ)

Find the sum: 2 + 9 + 16 + ... + 37
iris [78.8K]

Step-by-step explanation:

Sum of arithmetic terms = n/2 × [2a + (n - 1)×d], where 'a' is the first term, 'd' is the common difference between two numbers, and 'n' is the number of terms.

this is the same as n/2 × (a1 + an), because

an = a1 + (n-1)×d

so, for the series above :

a or a1 = 2

d = 7, as every new term is the previous term plus 7.

for n

37 = a1 + (n-1)×d = 2 + (n-1)×7

and now solve for n

35 = 7n - 7

42 = 7n

n = 6

so, the sum of all terms is

6/2 × (2+37) = 3×39 = 117

One-third of 2c subtracted from five times nine
SOVA2 [1]
<span>One-third of 2c subtracted from five times nine
1/3 of 2c subtracted 5 x nine
1/3 x 2c - 5(9)
=1/3 x 2c - 45
=2c/3 - 45
if we solve for c,
2c/3 = 45
2c = 45 x 3
2c = 135
c = 135/2 
c = 67.5</span>
