Answer:
x = -3/13
Step-by-step explanation:
cross multiply
4x + 6 = 30x + 12
combine like terms
-6 = 26x
x = -6/26 = -3/13
<span>x2 + 4
=5^2 +4
= 25+4
=29
answer is 29</span>
4(4+2) + 5(5+3)
4x6 + 5x8
24 + 40
64 is your answer
Step by step. :)
STEP
1
:
Equation at the end of step 1
0 - 7n • (n - 7) = 0
STEP
2
:
Equation at the end of step 2
-7n • (n - 7) = 0
STEP
3
:
Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2 Solve : -7n = 0
Multiply both sides of the equation by (-1) : 7n = 0
Divide both sides of the equation by 7:
n = 0
Solving a Single Variable Equation:
3.3 Solve : n-7 = 0
Add 7 to both sides of the equation :
n = 7
This is what i got! if i’m wrong i’m so sorry
but i tried. have a amazing day☺️☺️
Answer: a) 15625, b) 0.2, c) 625, d) 0.008.
