Answer:
Step-by-step explanation:
Apply Distributive property:
Add like terms and then add 63 to both sides of the equation:
Pick the coefficient of the x term, divide it by 2 and square it:
Add it to both sides of the equation:
Rewriting the left side as a squared binomial, we get:
Apply square root to both sides:
And finally we need to add 1 to both sides of the equation. Then we get:
<h3>Correct Response;</h3>
- <u>The drawing of the front and side elevation is attached</u>;
The given scale = 2 squares to 1 m
Number of squares in the plane on which the front elevation is to be drawn = 16 squares
<h3>Front elevation;</h3>The number of squares in the width of the front elevation = 4 squares
The number of squares in the front part closest to the observer = 4 × 1 squares
Number of squares in the slant surface of the = 3 squares by 4 squares
- <u>Please find attached the drawing of the </u><u>front elevation</u><u> of the given </u><u>diagram</u>.
Using the same pattern as above, we have that the side elevation is given as follows;
The width of the lower side of the side elevation = 2 meters = 4 squares
The height of the side elevation = 2 meters = 4 squares
- <u>Please find attached the drawing of the required front and side elevation</u>;
