0.7 Is An Irrational Number, Not A Rational Number
Answer: The sale price for an exercise bicycle is 182
the sale price for the weights is 84
Step-by-step explanation:
260 x .3= 78
260-78=182
than for the weights i did
120 x .3= 36
120- 36= 84
2^n = 88
To solve an equation with a variable in the power you have to use logs.
Take the log of both sides.
log 2^n = log 88
Using the power rule of logs, bring the n to the front, it becomes a coefficient.
n* log 2 = log 88
Divide both sides by log 2
n = (log 88)/(log 2)
n = 6.4594
Answer:
Option C is correct, i.e. 16x² + 24xy + 9y² = (4x + 3y)²
Step-by-step explanation:
Perfect square trinomial is an algebraic expression of three terms which can be combined into a squared binomial like (a+b)^2 = a^2 + 2ab + b^2.
From the given options, we can eliminate first two options because they have only two terms (they are not trinomials).
Checking 3rd option:- 16x² + 24xy + 9y²
16x² + 24xy + 9y² = (4x)² + 2(4x)(3y) + (3y)²
16x² + 24xy + 9y² = (4x + 3y)²
Checking 4th option:- 49x² - 70xy + 10y²
49x² - 70xy + 10y² = (7x)² - 2(7x)(5y) + 10y²
Hence, option C is correct, i.e. 16x² + 24xy + 9y² = (4x + 3y)²
