Answer:
-49
Step-by-step explanation:
The length of a face from the top of the forehead to the chin is 17 feet.
the width of the phases to feet given that and video Skies T-shirt has a length of 29 inches and a width of 20 in
so, the length of the face must fit the length on the t-shirt
So, the scale will be
so, the drawing scale = 29 inch : 17 feet
feet = 12 inch
so, 29 inch : 17 * 12 inch
so, the drawing scale = 29 : 204
so, the length of face will not above 29 inch
and the width not above 20 inch
Answer:
C.
Step-by-step explanation:
Most people do not want personal information about sensitive topics revealed about themselves, so Topic A requires anonymity.
With non-sensitive topics, people are usually comfortable with revealing their identity, so Topic B doesn't require anonymity.
The first one is a rectangle, second is a circle, third is a triangle, and fourth is a square.
You're solving a system here, easy peasy. Solve the second equation for y to get y = 2 - 3x. Now in the first equation, sub in this y value where you see a y and now the equation is in terms of x only: x^2 + (2-3x)^2 = 20. You have to FOIL out the (2-3x)^2 first to get x^2 + 4 - 12x + 9x^2 = 20. Now combine like terms to get 10x^2 - 12x + 4 = 20. Move the 20 over by subtraction to get
10x^2 - 12x - 16 = 0. Factor this now, taking a 2 out first: 2(5x^2 - 6x -8)=0 and you get factors of 2(x-2)(5x+4)=0. x=2 or x = -4/5. If x = 2, then y = -4. If x = -4/5, then y = 22/5
