Factor:
40a^2 - 32a

for those who don’t know ^2 means squared or to the power of two

8a(5a - 4)

Step-by-step explanation:

To factor this expression, see what numbers and variables these two terms have in common. I can see that they both have the variable a, so a can be factored out.

40 and -32 also have 8 in common, because they are both cleanly divisible by 8.

Now we can factor 8a out of 40a^2 - 32a. Think of how many times 8a goes into 40a^2 and -32a.

8a(5a - 4)

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
