Answer:
18 + 38 = 56 x 16 = 896 divided by 2 = 448cm
Answer:
-6
30
22
8x² + 18x + 4
8x² - 2x - 6
Step-by-step explanation:
f(x) = 8x² + 2x - 6
f(0) = 8(0²) + 2(0) - 6 = -6
f(2) = 8(2²) + 2(2) - 6 = 32 + 4 - 6 = 30
f(-2) = 8 × (-2)² + 2(-2) - 6 = 32 - 4 - 6 = 22
f(x + 1) = 8(x + 1)² + 2(x + 1) - 6 = 8(x² + 2x + 1) + 2x + 2 - 6 = 8x² + 18x + 4
f(-x) = 8(-x)² + 2(-x) - 6 = 8x² - 2x - 6
Answer:
46800
Step-by-step explanation:
46821 nearest 100s
look for the tens it is less than 5 so its 800 and the numbers written before the 100s would remain the same
1-10/9-2=-9/7
So, the slope is -9/7
X(x+3)-7(x+3)
x2+3x-7x-21
x^2-4x-21
