Use inverse operations to solve the following: 4.9 + z = -9

1 answer:

5 0

The answer is z = -13.9

In order to solve this, you need to use inverse operations. The inverse operation of addition is subtraction. So, this is the function we'll use

4.9 + z = -9 ----> subtract 4.9 from both sides

z = -13.9

jacks tent is shaped like an isosceles triangle. the height of the tent measures 7 feet and the diagonal side measures 9 feet. f

Maru [420]

Answer:

$8\sqrt{2}\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

Remember that

An isosceles triangle has two equal sides and two equal interior angles

In the isosceles triangle ABC

Applying the Pythagorean Theorem

Let

b ----> the length of the tents base

$9^2=7^2+(b/2)^2$

$(b/2)^2=9^2-7^2$

$(b^2/4)=32$

$b^2=128\\\\b=\sqrt{128}\ ft$

simplify

$b=8\sqrt{2}\ ft$

P^2 - 4p - 32 / p + 4, simplify the rational expression. state any restrictions

dusya [7]

Answer:

The correct answer is: p - 8 ∧ restriction p ≠ -4

Step-by-step explanation:

(p² - 4 p - 32) / ( p + 4)

The existence of this rational algebraic expression is possible only if it is:

p + 4 ≠ 0 => Restriction is p ≠ -4

(p² - 4 p - 32) / ( p + 4) = (p² - 8 p + 4 p - 32) / (p + 4) =

= (p (p -8) + 4 (p -8)) / (p + 4)= (p - 8) (p + 4) / ( p +4) = p - 8

God with you!!!
