Cecilia simplified an expression. Her work is shown below.

(6 and one-half + 2 and three-fourths) minus 1.5 times (4.5 divided by 0.5)
Step 1 9 and one-fourth minus 1.5 times (4.5 divided by 0.5)
Step 2 7.75 times (4.5 divided by 0.5)
Step 3 7.75 times 9
Step 4 69.75

Where did Cecilia make her first mistake?
step 1

step 3
step 4

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

570, the answer is 570, hope it

$450 i think. hope this ☺
