Less than = subtraction = -
Product = multiplication
(42 + x) - 18
Step-by-step explanation:
Using pythagoras theorem
9^2 - 6^2 = x^2
Therefore X^2 = 81 - 36
= 45
Thus X = √45
X = 6.71
Ten and five hundredths in decimal form is 10.05
Answer:
Step-by-step explanation:
First, we can factor all of the following equations to turn that weird, huge looking thing into ÷ × . We know that division is simply multiplication by the reciprocal, so that whole equation will turn into × × . Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into which is our final answer, as it cannot be simplified further.
Hope this helped! :)
Get rid of all common factors.
36/4 = 9
x^9/x^7 = x^2
y^4/y^3 = y
