What is the solution set to the equation 4x2 – 16 = 0?
Answer:
2
Step-by-step explanation:
add 16 to zero
4x2=16
Divide 4x by 2 and 16 by two
4x=8
divide 8 by 4
x=2
Answer:
x = ± 2
Step-by-step explanation:
Given
4x² - 16 = 0 ( add 16 to both sides )
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
solutions are x = - 2, x = 2

ILL MARK BRAINIEST IF YOU DO ONLY NUMBER 8 DO NOT DO 7!!!!
Answer and Step-by-step explanation:
8. We want to solve for a of the trapezoid area formula.
A = [tex]\frac{h}{2} (a + b)[/tex]
First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].
[tex]\frac{2A}{h}[/tex] = a + b
Now, we need to subtract b from both sides.
[tex]\frac{2A - b}{h}[/tex] = a
We get the answer to be:
I. a = [tex]\frac{2A - b}{h}[/tex]

whats 7 over 4 =35 over m in solving proportions NO LINKS PLZ
Hey there!
7/4 = 35/m
CROSS MULTIPLY BOTH of your NUMBERS
7(m) = 4(35)
7(m) = 7m
4(35) = 140
NEW EQUATION: 7m = 140
DIVIDE 7 to BOTH SIDES
7m/7 = 140/7
CANCEL out: 7/7 because that gives you 1
KEEP: 140/7 because that gives you the value of m
140/7 = m
Solve above and you have the answer of m
140/7 = 20
Therefore, the value of m = 20
Answer: m = 20

Answer:
x = 41
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 90 + 49 = 180
x + 139 = 180
x = 180 - 139
x = 41
