Answer:
The correct answer is c) 18 centimeters
Step-by-step explanation:
Given:
A = 18 cm²
We know that the formula for calculating area of a rectangle is
A = a · b where a is length and b is width
Possible choices is 6 · 3 and 9 · 2
Formula for calculating perimeter is
P = 2 ( a + b)
P₁ = 2 (6 + 3) = 2 · 9 = 18 cm²
P₂ = 2 (9 + 2) = 2 · 11 = 22 cm²
The obvious choice is P₁ = 18 cm²
God with you!!!
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
y=180-109=71
In a triangle, the sum of angles is 180.
So, x=180-71-44=65
x=65
Answer:
seirously I don't know if that's an "x" or a multiplication sign
Step-by-step explanation:
[3² x(189/9)]-32
9. 21x - 32
189x - 32
x = 189/32
x = 5.29/32
[3² x(189/9)]-32
9x21-32
189-32
157
Answer:
A
Step-by-step explanation:
a = 3n-30 solve for 'n'
a + 30 = 3n
n = (a+30)/3
n(a) = (a+30)/3
