The given expression is :
2xx+3-5(x-2)
We know that, 
Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
−3b+2.5=4
Subtract 2.5 from both sides.
−3b+2.5−2.5=4−2.5
−3b=1.5
Divide both sides by -3.
−3b/−3 = 1.5/−3
b=−0.5
We have that
cos A=0.25
so
A=arc cos (0.25)-------> using a calculator----> A=75.5225°
Round to the nearest hundredth-----> A=75.52²
the answer is
the option <span>75.52°</span>
Answer:
89
Step-by-step explanation:
7^2=49
49+4=53
6^2=36
53+36=89
Answer:
I have no idea but I suggest making the rule to round the output to the nearest tenth because all the numbers on there have a 9 at the end.
Hope I helped, if I'm right please give brainliest because I cant level up until I get 2 more ;(
<3 Enjoy,
