Answer:
70 m^2
Step-by-step explanation:
The key shows that each square side on the grid measures 2 m. The base of the triangle measures 7 grid square sides, so it measures 14 m. The height of the triangle measures 5 grid square sides, so it measures 10 m.
area of triangle = bh/2
area = (14 m)(10 m)/2
area = 140 m^2/2
area = 70 m^2
<u>Answer:</u>
3 months
<u>Explanation:
</u>
Amount saved in Gina’s saving account= 250
Amount Gina puts in her account each month= 4% of 3100
=
= 4 × 31
= 124
Hence total amount added in each month =124
Therefore money credited x months
= 250 + 124 x
Amount saved in Rodger’s account = 350
Amount Rodger puts in his account each month = 3% of 2900
=
=87
Hence total amount added in each month = 87
Therefore money credited x months
=350 + 87 x
Now to calculate the nearest month when Gina have more in her account than Rodger does
=Amount of money credited in x months in Gina’s account ≥ Amount of money credited in x months in Rodger’s account
=250+124 x ≥ 350+87 x
=37 x≥100
= x≥2.78
=3

The Julia age will be 39 years old if In 2021,Julia is 14 years old. Michael is 2.50 times as old as Julia.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the age of the Julia is x years when Michael is 60
Julia's age = 14 years in 2021
Age of Michael = 2.50×14 = 35 years
Increase in age Michael of 60 – 35 = 25
x = 14+25 = 39 years
Thus, the Julia age will be 39 years old if In 2021,Julia is 14 years old. Michael is 2.50 times as old as Julia.

Ok so,
Simplifying
4x + 4y + 4z + 4 = 0
Reorder the terms:
4 + 4x + 4y + 4z = 0
Solving
4 + 4x + 4y + 4z = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + 4x + 4y + -4 + 4z = 0 + -4
Reorder the terms:
4 + -4 + 4x + 4y + 4z = 0 + -4
Combine like terms: 4 + -4 = 0
0 + 4x + 4y + 4z = 0 + -4
4x + 4y + 4z = 0 + -4
Combine like terms: 0 + -4 = -4
4x + 4y + 4z = -4
Add '-4y' to each side of the equation.
4x + 4y + -4y + 4z = -4 + -4y
Combine like terms: 4y + -4y = 0
4x + 0 + 4z = -4 + -4y
4x + 4z = -4 + -4y
Add '-4z' to each side of the equation.
4x + 4z + -4z = -4 + -4y + -4z
Combine like terms: 4z + -4z = 0
4x + 0 = -4 + -4y + -4z
4x = -4 + -4y + -4z
Divide each side by '4'.
x = -1 + -1y + -1z
Simplifying
x = -1 + -1y + -1z
