The answer would be 40
-4(-2) = 8
8(5) = 40
15x = 3x + 120 (subtract both sides by 3x)
12x = 120 (divide both sides by 12)
x = 100
It’s A since 7/8 x (-16) is -14 then -14 x (-7) is 98 and 98 x (-1/14) is -98/14 which gets -7
Answer:
it would cost £15
Step-by-step explanation:
12 ÷ 4 = 3
3 × 5 = 15
1. y^2 - 3y - 5 - (-y^2 - 7y + 4) = y^2 - 3y - 5 + y^2 + 7y - 4 =
2y^2 + 4y - 9 <===
2. 6xy^3z * 3x^2yx^2 = 18x^5y^4z
3. -3x^3(-2x^2 + 4x - 3) = 6x^5 - 12x^4 + 9x^3
4. (6p + 2)^2 = (6p + 2)(6p + 2) = 36p^2 + 12p + 12p + 4 =
36p^2 + 24p + 4.....coefficient is 24
5. (x - 5)(x^2 - 2x - 6) = x(x^2 - 2x - 6) - 5(x^2 - 2x - 6) =
x^3 - 2x^2 - 6x - 5x^2 + 10x + 30 =
x^3 - 7x^2 + 4x + 30 <===
