Answer:
Claim 1
Step-by-step explanation:
Lateral Area means Area of all four triangles
Now area of 1 triangle = ![\frac{\sqrt{3}}{4} a^2 = \frac{\sqrt{3}}{4} 8^2](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B4%7D%20a%5E2%20%20%3D%20%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B4%7D%208%5E2%20)
=
square meters
Now for four triangles we multiply by 4
So
Lateral area of pyramid =
m^2
that is Option D
Q1. The answer is 4(2x - 3)(2x + 1)
16x² – 16x – 12 = 4 * 4x² - 4 * 4x - 4 * 3 =
= 4(4x² - 4x - 3) =
= 4(4x² + 2x - 6x - 3) =
= 4(2x * 2x + 2x - (2x * 3 + 3)) =
= 4(2x(2x + 1) - (3(2x + 1))) =
= 4((2x + 1)(2x - 3)) =
= 4(2x - 3)(2x + 1)
Q2. The answer is 3(x + 8)(x - 1)
3x² + 21x – 24 = 3 * x² + 3 * 7x - 3 * 8 =
= 3(x² + 7x - 8) =
= 3(x *x - x + 8x - 8) =
= 3((x(x - 1) + 8(x - 1)) =
= 3(x + 8)(x - 1)
Answer:
slope is 3 Y is -2
Step-by-step explanation:
Whenever a number is in "x" its slope. The number always after that is Y so slope is 3 and Y is -2
