Answer:
12
Step-by-step explanation:
Area of triangle formula is b*a (1/2)=A
b is height for non-right triangles
6*4(1/2)=A
24(1/2)=A
12=A
Answer:
Step-by-step explanation:
We want to factorize:
Where a=9, b=36, and c=11
ac=9×11=99
To factors of 99 that sums to 36 are 3,33
We split the middle term to get:
We factor by grouping
The factorization is
Plug 2 for y in the equation given.
x + 3(2) = 7
x + 6 = 7
Subtract six from both sides to isolate x.
x = 1
The ans is d
coz set A is subset of setB
