Base=x+7 Height=x Area=60. 60=((x+7)(x))/2----->60=(x^2+7x)/2
120=x^2+7x X^2+7X-120=0. QUDRATIC FORMULA: -7+/- SQRT(49+480)/2
(-7+/-23)/2... 8 and -15. -15 ISNT the answer because you cant have a negative length. X=8 Base=8+7---->15 Height=8
Answer:
Where a = 2 , b= 3, c= -5, replacing we have this:
And simplifying we got:
And the two solutions are:
And the correct options are:
B and C
Step-by-step explanation:
We have the following equation given:
And if we use the quadratic formula given by:
Where a = 2 , b= 3, c= -5, replacing we have this:
And simplifying we got:
And the two solutions are:
And the correct options are:
B and C
You can first take a y out so..
y(4y^2+19y+12) when you factor this you get
Y(4Y+3)(Y+4)
I hope this helps
