Answer:
30
Step-by-step explanation:
5x-1=149
5x=149+1=150
5x=150
x=150/5
x=30
Step-by-step explanation:
The GCF of 28 and 80 is 4.
<u>Distribute 4 for 28 and 80, then solve:</u>




X^2+3x=24, halve the linear coefficient, square it, and add it to both sides
In this case (3/2)^2=2.25
x^2+3x+2.25=26.25 now the left side is a perfect square...
(x+1.5)^2=26.25 take the square root of both sides
x+1.5=±√26.25 subtract 1.5 from both sides
x=-1.5±√26.25
x=-1.5-√26.25 and -1.5+√26.25
x≈ -6.62 and 3.62
So for number 2 i am 100% on which the area of the triangle is 6.
and then 1 i think not 100% sure is an acute angle again not 100%
then 3. it don't make sense to me so idk about that 1 srry.
~Good Luck~
