Answer:
-1 3/4
Step-by-step explanation:
3/4 + (-2 1/2)
3/4 - 2
-1 3/4
The sum of the angles of acute angles in a right triangle is 90°.
Therefore w have the equation:
Calculate m∠A:
<h3>Answer: 67°</h3>
The area of this is the length times the width times height?
Idk man
The equation for it is...
f-1(x)=-x2-7
You just multiply both sides by -1
To solve the give logarithm we proceed as follows;
log7(3x^3+x)-log7(x)=2
this can be written as:
log7[(3x^3+x)/(x)]=2
but;
log7(49)=2
thus;
log7(3x^3+x)/x=log7(49)
hence canceling log7 we get:
(3x^3+x)/x=49
This can be simplified further to get:
3x^2+1=49
3x^2=49-1
3x^2=48
x^2=48/3
x^2=16
getting the square root of both sides we get:
x=4
the answer is x=4
