The problem is that 7^2 is 7*7, and the same for 8^2. The right answer is the square root of 15, or 3.87

He/she forgot that 8^2=64 not 16, and 7^2=49 not 14. As a result, the correct answer is:
a^2+b^2=c^2
7^2+b^2=8^2
49+b^2=64
b^2=15
b≈3.9 cm. Hope it help!

Help solve these please 1.w + 10 = 25
4vir4ik [10]

Answer:

1. w = 15

2. b = 4.8

3. s = 9.7

4. p =15

5. m = -3.2

Step-by-step explanation:

1.w + 10 = 25

we have to find the value of w, so moving 10 from left side to right side

w= 25 - 10

w = 15

2. 7.2 + b = 12

we have to find the value of w, so moving 7.2 from left side to right side

b= 12 - 7.2

b= 4.8

3. 5.3 + s = 15

s= 15 - 5.3

s= 9.7

4.p + (-25) = -10

p-25 = -10

p= -10 + 25

p= 15

3. m + (-1.6) = -4.8

m - 1.6 = -4.8

m = -4.8 + 1.6

m= -3.2
