father=180
father and daughter is 7 times daught
father+x=7x
180+x=7x
D is answer
and daughter=30lb
Answer:
4m, 4m, and 5 m
Step-by-step explanation:
From the information give;
- Two sides of a triangle are equal in length
- The third side is 3 m less than the common length
- Perimeter of the rectangle is 13 m
We are required to determine the dimensions of the triangle;
- Assuming the common sides are x m each
- Then, the third side will be (2x-3) m
- Perimeter of a triangle is equal to the sum of the lengths of the three sides
Therefore;
(2x-3) + x + x = 13 m
4x - 3 = 13m
4x = 16 m
x = 4 m
and, 2x-3 = 5 m
Therefore, the lengths of the three sides of the triangle are 4m, 4m, and 5 m

Answer:
A
Step-by-step explanation:
given a quadratic function in standard form
y = ax² + bx + c (a ≠ 0 ) then the x- coordinate of the vertex is
x = - 
y = 2x² + 8x + 1 ← is in standard form
with a = 2 , b = 8 , then
x = - 
= - 2
substitute x = - 2 into the equation for corresponding y- coordinate
y = 2(- 2)² + 8(- 2) + 1 = 2(4) - 16 + 1 = 8 - 16 + 1 = - 7
vertex = (- 2, - 7 )
