Total area = area rectangle + area of the triangle
= 8 * 13 + 0.5* 6 * (14-8)
= 122 unit^2
Multiplication and parentheses assuming the parentheses close in the second one
Answer:
x=3 , x= -2
Step-by-step explanation:
x^2 -x-6 =0
to solve to find the X's we need to factor.
to factor we need to find gcf.
since this problem has no coefficient in front of the x there is no GCF.
So we need to find the multiples of -6
What times What = -6
-3 and 2 = -6
we know x would need to be foiled to create x^2 so x will be in the parenthesis.
(x ) (x )
now we want to put the multiples into parenthesis
(x-3) (x+2)
but we need to set x-3 and x+2 = to 0
the 0 product property.
x-3=0
+3 +3
x=3
x+2=0
-2 -2
x=2
I assumed that the unit of measure is ft.
Front+back:
S1=2×(4×3.5/2)=4×3.5=14ft²
2 sides+base:
S2=3×(9×4)=9×12=108ft²
Total area: 14+108=122ft²
