Factorise 4b^2 + 16b
lubasha [3.4K]
Factorise 4b² + 16b  ⇒ 4b(b+4)

expand (a-1)(a-2) ⇒ a(a-2) - 1(a-2) ⇒ a² - 2a - 1a + 2 ⇒a² - 3a + 2

factorise x² + 8x + 7 ⇒(x + 1) (x + 7)

evaluate y⁶ / y² ⇒ y * y * y * y * y * y / y * y = y⁴

if x = -1 and y = 5, find z when z = x² + 2y² ;
z = -1² + 2(5²) ⇒ 1 + 2(25) ⇒1 + 50 = 51

Make x the subject: y = 4x - 3
     y = 4x - 3
<u>+3            +3</u>
3 + y = 4x
<u>÷4        ÷4    </u>
(3+y)/4 = x

Find the equation of the line passing through the point (1,−5) and perpendicular to y=18x+2
sleet_krkn [62]

Step-by-step explanation:

m1.m2 = -1

18.m2 = -1

m2 = -1/18

formula = y - y1 = m2 ( x - x1)

y - (-5) = -1/18 ( x -1)

y + 5= -1x/18 +1/18

y = -1x/18 -89/18

The quotient of a number and negative eight is five-eighths. Find the number.
max2010maxim [7]

Answer:

-64/5

Step-by-step explanation:

Basically, the word "quotient" means the answer to a division problem. Therefore, its a division problem, so you have to work backwards with multiplication. -8 times a number is 5/8, so the other number is going to be negative.

The number is -64/5
