Answer:
Step-by-step explanation:
45+8x+21+90=180 degree(sum of interior angles of a triangle)
156+8x=180
8x=180-156
8x=24
x=24/8
x=3
Answer:
There is a few ways to answer this:
The actual and simple way: 19
The way we use for fun, (meme way): 910
Hey!
Area is equal to length × width. First find the area of the rectangle.
The area of the rectangle is 14.04 mm². That means the area of the square is also 14.04 mm². In a square, all 4 sides are the same. The length and width are the same.
Try all choices and see which is the closest
The 1st choice is the closest.
You can add them like this:
so if 156 + 213 + 109 was the equation then you would
first put them in order from biggest to smallest
213
156
+109
-----------
then add:
¹ ← ←
213 ↑
156 ↑
+109 ↑
---------↑ ( carry the 10 )
478 (add the ¹ )
then you get the answer 478!
hope that helps :)
Answer:
4t^2 - 32t + 64.
Step-by-step explanation:
f(x) = 4x2 – 8x + 4
f(t - 3) = 4(t - 3)^2 - 8(t - 3) + 4
= 4(t^2 - 6t + 9) - 8t + 24 + 4
= 4t^2 - 24t + 36 - 8t + 28
= 4t^2 - 32t + 64.
