That square in the corner means that this is a right angle (which is 90 degrees). If you make this into an equation you will have...
66 + x + 2 = 90
combine like terms
68 + x = 90
subtract 68 from both sides
x = 22
Hope this helps :)
350 grams of magic steel and 350 grams of dragon alloy #33 is needed to make 700 grams of Dragon alloy #18.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of magic steel and y represent the amount of alloy #33, hence:
(0 * x) + (y * 0.28) = 700(1 - 0.86) (1)
Also:
x + (1 - 0.28)y = 0.86(700) (2)
From both equations:
x = 350, y = 350
350 grams of magic steel and 350 grams of dragon alloy #33 is needed to make 700 grams of Dragon alloy #18.

Step-by-step explanation:
Area of a rectangle is given by:
where
l is the length and w is the width of the rectangle
As per the statement:
To find the dimensions of a rectangle of area 8 + 16x and width 4 .
Step 1.
Step 2.
Step 3.
Step 4.
Dimensions of the rectangle are 4 and 2+ 4x
Since, the student make an error in the Step 2
Therefore, the correct step is, 4(2) + 4(4x)
