answer:
52
step-by-step explanation:
- we can use the 45-45-90 triangle theorem for this: x, x, x
this is because this is a square
- squares have two sides of the same length, and the diagonal is different
- the x's stand for the sides, whereas the x stands for the diagonal
x = 26
x = 13
- now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4
13 X 4 = 52
1x+5 ....................
a) 13
b) 0
c) 1
d) 4/9
<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)
Given:
f(x)= 2x+3 and g(x)= x²-5.
a) (f+ g)(3)
= f(3)+ g(3)
= 2(3)+3 + (3)²-5
=6+3+9-5
=13
b) (f-g)(4)
= f(4)- g(4)
= 2(4)+3 - (4)²+5
=8+3-16+5
= 0
c) (fg)(-2)
= f(-2)*g(-2)
=[ 2(-2)+3][(-2)² -5 ]
=(-1)(-1)
= 1
d) (g/f)(3)
= g(3)/f(3)
= 3²-5/ 2(3)+3
= 4/9

Answer:
The two numbers are 24 and 32
Step-by-step explanation:
We can use the variable x
3x : 4x, would be a ratio of 3/4
now subtract 4 from both
3x - 4 : 4x - 4 = 5/7
3x-4 / 4x-4 = 5/7
cross multiplication
7(3x - 4) = 5(4x - 4)
21x - 28 = 20x - 20
x = 8
Two numbers are;
3x, 4x
3(8), 4(8)
24, 32
24/32 = 3/4
20/28 = 5/7
