bonufazy [111]3 years ago
3 0

Answer:

1.5 ft

Step-by-step explanation:

Use the Pythagorean theorem and rearrange it to find the third length.

3.6^2 + x^2 = 3.9^2

3.9^2 - 3.6^2 = x^2

15.21 - 12.96 = 2.25

sqrt 2.25 = 1.5

x = 1.5

22. Francisco is three years more than twice Jenna's age. Harrison is two years less than three times Jenna's age.
Jet001 [13]

Answer:

An expression for Francisco's age in terms of a is (2a+3)

An expression for Harrison's age in terms of a is (3a-2)

An expression for the sum of all  three ages, in terms of a is (6a+1)

Step-by-step explanation:

Let

a -----> Jenna's age

b -----> Francisco's age

c -----> Harrison's age

we know that

Francisco's age is two times Jenna's age plus three years

b=2a+3 -----> equation A

Harrison's age is three times Jenna's age minus two years

c=3a-2 ----> equation B

The sum of all  three ages, in terms of a is

(a+b+c) -----> equation C

substitute equation A and equation B in equation C

a+(2a+3)+(3a-2)

Combine like terms

(a+2a+3a)+(3-2)

6a+1

therefore

An expression for Francisco's age in terms of a is (2a+3)

An expression for Harrison's age in terms of a is (3a-2)

An expression for the sum of all  three ages, in terms of a is (6a+1)
