2^3x = 172
3x log 2 = log 172
3x = 7.4263
x = 2.475
i am a mathematics teacher. if anything to ask please pm me
You didn’t leave a picture so i can’t
Step-by-step explanation:
To leave answer in positive exponents, just leave the answer inverse of the negative exponents.
Answer:
In bold.
Step-by-step explanation:
a. (x+5)^2 – 3x(x+5) x+5 is common
= (x + 5)(x + 5 - 3x)
= (x + 5)(5 - 2x)
b. (x + 5)(5 - 2x) = 0
x = -5, 2.5.
2a. Area of the square = (x + 5)^2
Area of triangle AEB
= 1/2 * base * height
I am assuming that H is the centre of AB , so
Area = x*x
= x^2.
2b
6x^2 = (x + 5)^2
6x^2 = x^2 + 10x + 25
5x^2 - 10x - 25 = 0
x^2 - 2x - 5 = 0
x = [-(-2) +/- sqrt(2^2 - 4*1*-5)] / 2
x = -1.45, 3.45.
(we ignore the negative).
Factors of a number are integers that when multiplied together will equal the original number
Example: Factors of 36
1,2,3,4,6,9,12,18,36
1x36 = 36
2x18=36
3x12=36
4x9=36
6x6=36
