Both of them are the first answer choice
Answer:
a. Narrower
b. Shifts left
c. Opens up
d. Shifts up
Step-by-step explanation:
The original quadratic equation is y = x²
The given quadratic equation is y = 5·(x + 4)² + 7
The given quadratic equation is of the form, f(x) = a·(x - h)² + k
a. A quadratic equation is narrower than the standard form when the coefficient is larger than the coefficient in the original equation
The quadratic coefficient is 5 > 1 in the original, therefore, the quadratic equation is <em>narrower</em>
b. Given that the given quadratic equation has positive 'a', and 'b', and h = -4, therefore, the axis of symmetry <em>shifts left</em>
c. The quadratic coefficient is positive, (a = 5), therefore, the quadratic equation <em>opens down</em>
d. The value of 'k' gives the vertical shift, therefore, the given quadratic equation with k = 7, <em>shifts up.</em>
Answer:
52m²
Step-by-step explanation:
For this you would consider each face of the figure as a rectangle, and then multiply it by two.
Face 1:
3m×4m×2=24m²
Face 2:
4m×2m×2=16m²
Face 3:
3m×2m×2=12m²
Then you add each of them together to get the overall surface area
12m²+16m²+24m²=52m²
Therefore the final surface area is 52m²
Answer: e. 
Step-by-step explanation:
1. You have the following expression given in the problem:
2. To solve the exercise and find an equal expression, you must simplify that expression. Apply the Distributive property. Multiply the terms inside the parentheses by 
. Then, you obtain:
