Answer:
Step-by-step explanation:
l = 22
w = 70
Perimeter =2l + 2w
= 2*22 + 2*70
= 44 + 140
= 184 units
This equation has to be False
Answer:
x = 1 and vertex = (1, - 7 )
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
The the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = -
y = 4x² - 8x - 3 ← is in standard form
with a = 4, b = - 8 , then
x = - = 1
That is equation of axis of symmetry is x = 1
Substitute x = 1 into the function for y- coordinate of vertex
y = 4(1)² - 8(1) - 3 = 4 - 8 - 3 = - 7
vertex = (1, - 7 )
Answer:
5
Step-by-step explanation:
Since both triangles are similar, the ratio of their corresponding side lengths would be equal.
This implies that:
AB/40 = 8/64
Cross multiply
AB*64 = 40*8
AB*64 = 320
AB = 320/64
AB = 5
