Answer:
Step-by-step explanation:
(-2 + x)/2= 4
-2 + x = 8
x = 10
(2 + y)/2 = -3
2 + y = -6
y = -8
(10, -8) for endpoint H
Diagonal of a square is √2a
so,
√2 a = 12
a= 12/√2
and.. perimeter of a square is 4a
so,
peri = 4*12/√2
= 48/√2
=33.94cm
Answer:
Triangle - 21 units
Trapezoid - 65 units
Step-by-step explanation:
- Because this triangle and trapezoid are reflections of each other when split in half, remove the highlighted parts to make them a rectangle. When made into a rectangle, you can use the formula length * width to find the area of either shape (trapezoid or triangle).
- Note you won't be able to do this when solving for the area of ALL trapezoids and triangles.
If you want to increase something by 31% then...
100%+31%=131% or 1.31
you multiply it by 131% or 1.31. So for 429 grams...
429*1.31=561.99grams
If you increase 429 by 31%, you get 561.99 grams
Answer=561.99 grams
Answer:
159
Step-by-step explanation:
10^2+(3+5)^2-5
-> 100 + (3+5)^2 -5
-> 100 + 8^2 - 5
-> 100 + 64 - 5
-> 159
