Subtract 7x^2−5xy+8y2 from −2x^2−15xy+9y^2

Digiron [165]

Answer

Subtract $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$

then;

$-2x^2 -15xy+9y^2 - (7x^2 -5xy+8y^2)$

Remove the bracket we have;

$-2x^2 -15xy+9y^2 - 7x^2 + 5xy - 8y^2$

Like terms are those terms which have same variable to the same power.

Combine like terms;

$-9x^2 -10xy+y^2$

Therefore, Subtracting $7x^2 -5xy+8y^2$ from $-2x^2 -15xy+9y^2$ we get $-9x^2 -10xy+y^2$

16) w(x) = 4x + 4; Find w(x + 4)

Zina [86]

$\\ \tt\hookrightarrow w(x)=4x+4=4(x+1)$

Now

$\\ \tt\hookrightarrow w(x+4)=4(x+4+1)$

$\\ \tt\hookrightarrow w(x+4)=4(x+5)$

$\\ \tt\hookrightarrow w(x+4)=4x+20$

KonstantinChe [14]

Answer:

Step-by-step explanation:

Anything raise to the power zero is 1

Therefore,

$LHS\\\\ =2^3 \times 3^0 + 3^2 \times 2^0\\\\8 \times 1 + 9 \times 1 \\\\17$

LHS = RHS

Hence Proved
