==>?=2x²-10x+10
Answer:
d and e
Step-by-step explanation:
IV must have a pos x value and a negative y value
we can eliminate everything except d e & f
f is wrong bc it has a positive 3 value
Answer:
If the total cost of the 4 necklaces was 18.40 then that means in order to find out how much she spent on pendents she needs to subtract the amount of beads from from the total cost so,
18.40-11.20=7.20
And cause she made 4 necklaces she is going to need to divide 7.20 by 4 to find out the cost of money that she had spent on each necklaces pendants.
7.20÷4=1.80
Meaning that she had spent $1.80 on each necklaces pendants

Step-by-step explanation:
Answer:
1)107
2)43
Step-by-step explanation:
Triangles interior angles add up to 180 degrees. In the first one, the first two angles are 31and 42, and if interior angles add up to 180, the equation should be 31+42+x=180 x=107.
Second one is hardes. A square means a right angle, or 90 degrees. 180-90 is 90. Next, we have the two angles x, and x+4 We know that triangles interior angles add up to 180 degrees, so x+x+4+90=180 2x+94=180 2x=86 x=43
Hope this helps :D Please mark brainliest if correct :D
