X=80°
A triangle’s angle measurements always add up to 180°. So 180-70-30=80
The first rectangle has a length of 20cm and a width of 2cm for the area to be 40cm. so, the dimensions must be multiplied by 4 to equal 160cm.
2 tens, and 8 ones. I say this because 20 = 10 + 10 so, two tens. 8= 1+1+1+1+1+1+1+1 so, eight ones.
Answer:
a. y = -x² + 2x - 8
b. y = 
c. y = x³+ 3
Step-by-step explanation:
Shift the graph of the function y = x², 5 units down /look at the picture #1/.
/look at the picture #2/ - your answer
