Area = base * height = 35 square inches
When we make the dimensions 2.5 by 3.5 then,area = 2.5 * 3.5 = 8.75 square inches
35 / 8.75 = 4So, when we reduce the width AND the height by 2, the area decreases by 4.Why? Because when we are reducing 2 dimensions:area = width/ 2 * length / 2 = area / 4
Answer:
8 ≥ x+3 or x ≥ 12
Step-by-step explanation:
The sum of a number (additon) and 3 (x+3) is no more than (so less than or equal to eight) OR is more than 12 ( x is more than 12, x ≥ 12 )
Answer:
(f-g)(x)=-x^(2)+2x+8
the solutions are:
<em><u>x=4 or x=-2</u></em>
Step-by-step explanation:
(f-g)(x)=2x+1-(x^(2)-7)
(f-g)(x)=-x^(2)+2x+1+7
(f-g)(x)=-x^(2)+2x+8
does this help or should I solve for the zeros/solutions of this quadratic equation?
then:
-x^(2)+2x+8=0
-(x^(2)-2x-8)=0
x^(2)-2x-8=0
(x-4)(x+2)=0
<em><u>x=4 or x=-2</u></em>

Answer:
To find the left triangle we make the two right triangles equal 1 square, making the area of that 2x2 or 4
Then we take the uppermost triangle on the left and find the area of that which is 2x2 / 2 or 2. Then we find the right uppermost triangle which is 5x 2 /2 or 5. Then we take the rightmost triangle and find that 4x 4 /2 or 8. Then we add the square in the middle which is 3 x 4 or 12.
Add those area 4 + 2 + 5 + 8 + 12. You should get 31.
Hope that helps somewhat. You need to divide the shape into easily usable shapes like squares and triangles.
