Petri did the following problem but got the wrong answer. she needs to correct her mistake and turn the problem back in.

(5 - 3) ^2 ÷ 3 • 7 + 1
25 - 9 ÷ 3 • 7 + 1
25 - 3 • 7 + 1
25 - 21 + 1
4 + 1
5

what correction does petri need to make?

she needs to subtract 5 - 3 first.
she needs to multiply 3 times 7 before she divides.
she needs to add before she multiplies.
she needs to change 25 to 10.

Petri needs to subtract 5 - 3 first.

Step-by-step explanation:

Given :

To Find : What correction does Petri need to make?

Solution:

Second step :

is the correct second step

While Petri's second step is 25 - 9 ÷ 3 • 7 + 1

Petri did mistake

She needs to subtract 5 - 3 first.

Hence Petri needs to subtract 5 - 3 first.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
