Answer:
x = - [tex]\frac{7}{3}[/tex] , x = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Given
(3x + 7)(2x - 5) = 0
Equate each factor to zero and solve for x
3x + 7 = 0 ( subtract 7 from both sides )
3x = - 7 ( divide both sides by 3 )
x = - [tex]\frac{7}{3}[/tex]
and
2x - 5 = 0 ( add 5 to both sides )
2x = 5 ( divide both sides by 2 )
x = [tex]\frac{5}{2}[/tex]

Answer:
=1/5
Step-by-step explanation:
1/2 of 2/5
( 'of' means multiplication)
therefore: 1/2 of 2/5= 1/2×2/5
1/2×2/5=(multiply 2×1 & 2×5)
u get 2/10(simplify by 2 u get 1 by 2 you'll get 5)
therefore the answer = 1/5
hope u understand

Answer:
(x - 3)² = -9
Solution:
Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.
Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.
Answer:
x=3+3i, 3-3i
Step-by-step explanation:
-4(x-3)²+7=43
(x-3)(x-3)= x²-6x+9
-4(x²-6x+9)+7=43
-4x²+24x-36+7=43
-4x²+24x-29=43
-4x²+24x-72=0
-x²+6x-18=0
Quadratic formula: -b+√(b²-4ac) / 2a
-(-6)+√((-6)²-4(1)(18)) / 2(1)

A = 2^3 x 3 x 5
B = 22 x 3 x 52
(b) Write down the highest common factor (HCF) of A and B.
Answer:
Step-by-step explanation:
B = 22 × 3 × 52?—or is it supposed to be
B = 2² × 3 × 5² ?
A = 2² × 3 × 5
B = 2² × 3 × 5²
GCF = 2² × 3 × 5 = 60
A = 2² × 3 × 5
B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13
GCF = 2² × 3 × 5 = 60

The table below gives the dimensions of a bridge and a scale model of the bridge.
Find the scale factor of the model to the real bridge.
Write your answer as a fraction in simplest form.
Answer:
Scale factor = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Formula for the scale factor is,
Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]
= [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]
= [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]
= [tex]\frac{7}{35}[/tex]
= [tex]\frac{1}{5}[/tex]
Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]
