Answer:
x = ± 13
Step-by-step explanation:
Given
x² = 169 ( take the square root of both sides )
x = ± = ± 13
Since 13 × 13 = 169 and - 13× - 13 = 169
Yes it is a 90 degree rotation clockwise.
Answer:
top one
Step-by-step explanation:
i got it right :)
1. 2-1+5x4x11
5x4=20
2-1+20x11
20x11=220
2-1+220
2-1=1
1+220=221
2. 14/2-1+3
14/2=7
7-1+3
7-1=6
6+3=9
3. 3x8x2-42+5
3x8=24
24x2-42+5
24x2=48
48-42+5
48-42=6
6+5=11
This answer would be a cuboid because it has parallel,perpendicular,and diagonal cross sections
