Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
Answer:
combined variation
Step-by-step explanation:
we have
we know that
a)<u> in the interval </u>----> (0,∞)
If the value of x increase the value of y increase
so
Is a direct variation
b) <u>in the interval -</u>---> (-∞,0)
If the value of x increase the value of y decrease
so
Is a inverse variation
therefore
Is a combined variation
X^2 + x + 3x - 3
x^2 + 4x - 3
Therefore the coefficient of x in expansion is 4.
Hey!
What this question wants you to do is use PEDMAS, that is the order of operations, to get the answer.
P - Parentheses
E - Exponents
D - Division
M - Multipliation
A - Addition
S - Subtraction
So using PEDMAS, solve this problem by doing the operations first that come first, so you might want to start by solving 16 divided 2. (Division comes before multipliciation)
