Answer:
5x -11
Step-by-step explanation:
it says it there
The area of a square is A=s² (s being the side). Since you know this, you can write an equation.
A=(6a - 2b)²
Expanding this would give you,
A=(6a - 2b)(6a - 2b)
Then to solve this you would want to FOIL (Multiply first terms, multiply outer terms, multiply inner terms, multiply last terms)
36a² - 12ab - 12ab + 4b²
Then combine like terms,
36a² -24ab + 4b²
So the answer would be D
Answer:
solution:-
diameter of a cylinder (d) = 12 cm
length(h) = 30 cm
curved surface area of cylinder (csa) = ?
we know that ,
therefore , csa of cylinder = 2πrh
r = d/2
or, r = 12/2= 6 cm
Then, csa if cylinder = 2 ×22/7×30
= 2×22×30/7
= 1320/7
= 188.57 Square cm Ans,......
Answer:
m(JCA)
Step-by-step explanation:
C is the central angle here (the one in between)
so it will be m(JCA) or m(ACJ)
Side Angle Side Postulate. The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
