On number 10, you know that the whole side length is going to be 1/4 of 48 because 9 * 4 = 36. So, you can say that x will be equal to 12, since 1/4 of 48 is 12 and 12*2 + -12 = 12.
On number 11, you can say that 5x +5 = 40 because that is 5 times 8. So, you can solve for this to get x = 7 by subtracting 5 from both sides and then dividing both sides by 5. Hope this helps and let me know if you have more questions!
Answer:
6x^2 + 17x + 12.
Step-by-step explanation:
(3x + 4)(2x + 3)
= 3x(2x + 3) + 4(2x + 3)
= 6x^2 + 9x + 8x + 12
= 6x^2 + 17x + 12.
Answer: -1m²+81
Step-by-step explanation:
correct standard form means that the terms are ordered from biggest exponent to lowest exponent.The leading coefficient is the coefficient
of the first term in a polynomial in standard form.
FoR example, (9+ m) (-m+9) = *(m+9) (-m+9) *m(-m+9) +9 (-m+9)* -1.mm+9m +9(-m+9) * -1m² +9m +9(-m+9) *-1m²+9m- 9m +81
answer -1m²+81
