Answer:
Multiply both sides of the equation by 1/3
Step-by-step explanation:
3x^2+18x=21
The first step is to get the x term with a coefficient of 1, so divide by 3 on both sides of the equation
This is the same as multiplying by 1/3
1/3 * (3x^2+18x)=21*1/3
x^2 +6x = 7
Answer:
400 to 5 in simplest form
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 400 and 5 is 5.
400 ÷ 55 ÷ 5.
Reduced fraction: 801. Therefore, 400/5 simplified is 80/1.
C, 51 because acute angles are less than 90° but together the angles create a right triangle which is 90°.
