Answer:
189
Step-by-step explanation:
The pyramid has four triangular faces and a square base.
The area of a triangle is half its base times its height. The base of each triangle is 7, and the height of each triangle is 10. So the area of each triangle is A = ½ (7) (10) = 35.
The area of a square is the side length squared. The side of the square is 7. So the area of the square is A = (7)² = 49.
The total surface area is:
A = 4(35) + 49
A = 189
The solution for X when y= 0 is x=10,-10 because you substitute 0 for y> 0=x^2-100 then its going to be 100=x^2 so you'll get x=10 or x=-10
Answer:
Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.
Step-by-step explanation:
<u>Step 1: Factor</u>
256x^4y^2−y^2
y^2(256x^4 - 1)
y^2(16x^2 - 1)(16x^2 + 1)
<em>y^2(</em><em>4x + 1)(4x - 1</em><em>)(16x^2 + 1)</em>

Answer: Option B, Spencer did not factor the polynomial completely; 16x^2−1 can be factored over the integers.
Do you mean Y=|-3x- 2|-4 or Y=|-3x+2|-4
128 at 4 weeks
6 lb 3 oz born
There are 16 ounces in a pound
Multiply 16 by 6 you get 96
Add the three you get 99
He was 99 oz day of his birth
Now subtract the two
128-99
29
He gained 29 ounces
