Answer:
4
Step-by-step explanation:
First things first we will need to solve the square root.
We can check this by squaring 2.
= 2 x 2 = 4
Now that we have solved the square root, we are left with 2(2). 2 x 2.
2(2) = 4
2 = ?
2(2) = ?
4
x = 5.
I attached an image of my work!
Step 1: Subtract 8 from both sides
4x = 20
Step 2: Divide each side by 4
x = 5
Answer:
Step-by-step explanation:
sin 30+tan²(60)+sec²(45)
=1/2+ (√3)^2+(√2)²
=1/2+3+2
=5 1/2
=5.5
Answer:
Step-by-step explanation:
x^2=+5X=300
Let
x = the width of the rectangle
y = the length of the rectangle
we know that
the area of the rectangle is equal to
A=xy ___ equation 1
y=x+5 ___equation 2
substitute equation 2 in equation 1
------> given problem
so
the area of the rectangle is equal to
Solve the quadratic equation
we know that
The formula to solve a quadratic equation of the form is equal to
we have
so
substitute in the formula
The solution is
Find the value of y
y=x+5
Answer:
There are 360 degrees in one revolution, so a 270-degree clockwise rotation would be the same as a 90-degree counterclockwise rotation. Therefore, the rule would be to map (x, y) to (–y, x).
