Answer:
140°
Step-by-step explanation:
edge just did the assignment
It's kinda like using variables, but shapes in their place. Let's set the circle to x, the triangle to y, and the square to z. Now the equations say x+(y+z)=13, (y+z)=8, and x+y=7. First thing we can do it plug 8 into the first equation for y+z, getting x+8=13. Subtract 8 to both sides and x (or circle) equals 5. Plug 5 into the last equation, x+y=7 to solve for y, getting 5+y=7. Subtract 5 to both sides and y (or triangle) equals 2. Finally, plug two in for y in y+z=8, getting 2+z=8. Subtract 2 from both sides and z (or square) equals 6. Hope I've explained it clearly!!
Answer:
Step-by-step explanation:
x² + 4x - 1 - x =x² + 4x -x - 1 { bring the like terms together and add}
= x² + 3x - 1
Options A, B and D are true.
Answer:
1. 441 km in 45 sec have the same speed as Saige's spaceship.
2. 215 km in 25 sec does not have the same speed as Saige's spaceship.
3. 649 km in 110 sec does not have the same speed as Saige's spaceship. Step-by-step explanation:
Saige's spaceship 588/60= 9.8
441/45= 9.8 same
215/25= 8.6 not the same
649/110= 5.9 not the same
Hope this helps!
