Katie is 32 years old
add 5 to 11 and multiply 16 by 2 to get 32
I know nvm I do not it’s so hard
Answer:
A = 437 mm²
Step-by-step explanation:
The general formula for the area of a triangle:
A =
, where 'b' is the measure of the base and 'h' is the measure of the height
Given the dimensions of the triangle in the picture:
A =
= 437 mm²
The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
