(a) The perimeter of a rectangular garden is 302 m. If the width of the garden is 63 m, what is its length?
Length of the garden: Im
(b) The area of a rectangular window is 8118 cm?.
If the length of the window is 99 cm, what is its widtix
Width of the window: cn

a=88

b=82

Step-by-step explanation:

perimeter=2(l+w)

302=2(l+63)

302=2l+126

2l=176

l=88

A=l×w

8118=99×82

w=82

A. 87m

B. 82cm

Step-by-step explanation:

A = 87m because 63*2= 128 For the Width and 302 -128= 174 and 174/2= 87 which is the Length of the rectangular garden

B = 82cm because 8118/99= 82 Thus 82 is the length so 99*82= 8118

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
