Area of a triangle: A= 1/2(base)(hieght)
base=x
height= 6(base)+1= 6x+1
13= 1/2 × (x)(6x+1)
(get rid of 1/2 by multiplying each side by 2)
26= (x)(6x+1)
26= (x × 6x)= 6x² (x × (+1))= x
26= 6x² + x
0= 6x²+x-26
Are either of those the answers? If not, list the options and I will be able to tell you which one is correct. Hope this helped!
9x+11-4x+3=24
always combine like terms first. Combine all the x's and all numbers.
5x+14=24
Therefore, the answer is D.
D is wrong. D= 0.4 (roughly) A B and C are the same thing = 2.25 9 divided by 4=2.25 In math OF means TIMES (like multipling) and a fraction is dividing :) Hope this helps
Answer:
78.54
Step-by-step explanation:
the formula to calculate the area of a circle is
