Answer:Parallelogram, rhombus ,square
Step-by-step explanation:
You multiply the area by the scale factor twice. Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.
hope it helps!!!
X=20° is your answer
Step-by-step explanation:
X+3x+10°=90°
4x+10°=90°
4x=(90-10)°
X=80/4
X=20°
Answer:
x=2
Step-by-step explanation:
First use the distributive property on the right side... You should get then have 7x+30 = 2 + 6x + 30
Simplify further by combining like terms to get 7x + 30 = 32 + 6x
Now subtract 6x on both sides (6x - 6x cancels out) to get 1x + 30 = 32
Next subtract 30 from both sides(30-30 cancels out) to get 1x = 2
2 divided by 1 is 2 so x = 2
Answer:
t = 3 seconds
Step-by-step explanation:
This is a quadratic equation. First set it up and set it equal to 0 (the ground).
-16t² + 46t + 6 = 0
The quadratic formula is (-b ± √(b² - 4ac))/2a
a= -16
b = 46
c = 6
Plug those numbers into the equation and solve which will result in -.125 or 3.
The time of course can not be negative in this case. Therefore, t=3 seconds.
