Simplify the expression 4+2(6+1)+5(5-2)

33

Step-by-step explanation:

Use PEMDAS, so the first thing you solve is what's in the parenthesis.

(6 + 1) = 7

(5 -2) = 3

So now your equation looks like 4 + 2 x 7 + 5 x 3

Now multiply the numbers needed

2 x 7 = 14

5 x 3 = 15

So now it looks like 4 + 14 + 15

Simplify

4 + 14 = 18 + 15 = 33

33

Step-by-step explanation:

This is the answer because:

You can use PEMDAS or GEMS

PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

GEMS: Grouping (Parenthesis), Exponents, Multiplication and Division (whichever one comes first from left to right.), Addition and Subtraction (whichever one comes first from left to right.)

1) First, we have to do grouping (parenthesis)

(6+1) = 7

(5 - 2) = 3

New equation: 4 + 2 x 7 + 5 x 3

2) Next, we have to do multiplication

7 x 2 = 14

5 x 3 = 15

New equation: 4 + 14 + 15

3) Finally, add everything up.

4 + 14 + 15 = 33

Hope this helps! :D

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
