Answer:

Step-by-step explanation:

The triangle on the right is smaller than the one on the left, so the numbers on the right triangle are smaller. The numbers are being multiplied by 5 because...

side 5 times 5 = side 25 on the left triangle

side 6 times 5 = side 30 on the left triangle

so...

side 8 time 5 = side 40 on the left triangle which is the answer

Answer:

$\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4$

Step-by-step explanation:

Given the expression

$\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)$

solving the expression

$=-7x^0+5x^2-x+6-\left(-8x^2+x+3\right)$

apply the rule: $a^0=1,\:a\ne \:0$

$=-7+5x^2-x+6-\left(-8x^2+x+3\right)$

$=-7+5x^2-x+6+8x^2-x-3$

simplify

$=13x^2-2x-4$

Therefore, the simplified form is:

$\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4$
