The diagram shows a lawn with a fence along on edge

37.92 euros.

Step-by-step explanation:

First divide both parts into a square and a right triangle.

Then find the area of the square. 12*12=144 meters squared.

Next find the area of the triangle. 12*8=96/2=48

Sum. 144+48=192

Divide. 192/100= 1.92 cans of weedkiller.

Multiply. 1.92*19.75= 37.92 euros.

17²-8²=225

√225=15

1/2(12+20)×15=240m²

240÷100=2.4

3×19.75=£59.25

answer: the value of x is 7cm

step-by-step explanation:

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!
